a lot of research has gone into making small improvements on pressure ratio for a stage in an axial compressor. it took about 25 years to come from a pressure ratio of 1.15 to 1.23 per stage. is it worth the effort? take an axial compressor with total pressure ratio of 24 and explain in terms of number of stages and power to weight ratio of the gas turbine

Answers

Answer 1

The decision of whether it is worth the effort to make small improvements on pressure ratio for a stage in an axial compressor depends on various factors such as the specific application, the cost of the improvements, and the benefits that the improvements may provide.

In the case of a gas turbine with a total pressure ratio of 24, the number of stages required to achieve this pressure ratio would depend on the pressure ratio per stage. If each stage has a pressure ratio of 1.23, then the number of stages required would be:

24 / 1.23 = 19.51

Since the number of stages must be an integer, the gas turbine would require 20 stages to achieve a total pressure ratio of 24.

The power to weight ratio of the gas turbine is an important metric for assessing its efficiency and performance. Improving the pressure ratio per stage can result in a higher total pressure ratio for the gas turbine, which can lead to improved power output and efficiency. However, this improvement comes at the cost of additional weight and complexity in the form of additional compressor stages.

Therefore, the decision to invest in improving the pressure ratio per stage in an axial compressor should be made after considering the potential benefits in terms of improved power output and efficiency, as well as the costs associated with additional weight and complexity.

A parallel circuit has a resistance values of 1,200 ohm, 2,200 ohm, and 3,000 ohm. If the circuit has a total current flow of 0.25 Ampre. How much current flows through each of the resistors

Answers

In a parallel circuit, the voltage across each resistor is the same, while the current through each resistor is different.

To find the current through each resistor, we can use Ohm's Law:

I = V / R

where I is the current, V is the voltage, and R is the resistance.

Since the voltage is the same across each resistor in a parallel circuit, we can use the total current and the resistance values to find the current through each resistor.

Let's start with the first resistor:

I1 = V / R1
I1 = 0.25 / 1200
I1 = 0.00020833 A

Now, let's find the current through the second resistor:

I2 = V / R2
I2 = 0.25 / 2200
I2 = 0.00011364 A

Finally, let's find the current through the third resistor:

I3 = V / R3
I3 = 0.25 / 3000
I3 = 0.00008333 A

Therefore, the current flowing through the first, second, and third resistors are 0.00020833 A, 0.00011364 A, and 0.00008333 A, respectively.

Answers

In a concentric tube heat exchange with an area of 100 m2, 5 kg/s of water enters at 50°C and is heated by oil with a specific heat of 2.1 kJ/kg and a flow rate of 8 kg/s. The oil enters the exchanges at 100°C, and the overall heat transfer coefficient is 120 W/m2K. Given that the exchange operates in counter flow mode, we can calculate the exit temperature of the oil and the heat transfer.

First, let's determine the heat transfer rate (Q) using the formula Q = m_water * c_water * (T_out_water - T_in_water), where m_water is the mass flow rate of water, c_water is the specific heat of water (4.18 kJ/kgK), and T_out_water and T_in_water are the outlet and inlet temperatures of water, respectively.
Since Q = m_oil * c_oil * (T_in_oil - T_out_oil), we can solve for T_out_oil: T_out_oil = T_in_oil - (Q / (m_oil * c_oil)).
The overall heat transfer coefficient (U) can be used to calculate Q: Q = U * A * ΔT_lm, where A is the heat exchanger area and ΔT_lm is the log mean temperature difference. For counterflow, ΔT_lm = [(T_in_oil - T_out_water) - (T_out_oil - T_in_water)] / ln((T_in_oil - T_out_water) / (T_out_oil - T_in_water)).
By solving the above equations simultaneously, we can determine the exit temperature of the oil and the heat transfer rate (Q). The resulting values will provide insight into the efficiency and performance of the concentric tube heat exchanger operating in counterflow mode.

in what flight condition must an aircraft be placed in order to spin

Answers

In order for an aircraft to spin, it must be placed in a specific flight condition known as an aggravated stall. This occurs when the angle of attack of the aircraft is too high and the airflow over the wings becomes disrupted, causing a loss of lift.

As a result, one wing may stall before the other, creating an unequal lift distribution that can cause the aircraft to enter a spin. Pilots must be trained to recognize and recover from this dangerous situation in order to prevent accidents.
In order to spin, an aircraft must be placed in a specific flight condition known as a "stall." A stall occurs when the angle of attack is too high, causing a reduction in lift and an increase in drag.

In order for an aircraft to spin, it must be in a stall condition. A stall occurs when the angle of attack (AOA) is too high, causing the airflow over the wings to separate and the lift generated by the wings to decrease. When the AOA reaches the critical angle of attack, the airflow can no longer create enough lift to keep the aircraft in the air, and it begins to descend.

During a spin, one wing drops while the other rises, and the aircraft rotates around its vertical axis. This occurs when one wing continues to generate lift while the other does not, causing the aircraft to roll and yaw simultaneously.It is important to note that not all aircraft are designed to spin, and attempting to spin an aircraft that is not certified for it can be dangerous.

The bag itself is made of a thin, nylon fabric, which is folded into the steering wheel or dashboard or, more recently, the seat or door.

The sensor is the device that tells the bag to inflate. Inflation happens when there is a collision force equal to running into a brick wall at 10 to 15 miles per hour (16 to 24 km per hour). A mechanical switch is flipped when there is a mass shift that closes an electrical contact, telling the sensors that a crash has occurred. The sensors receive information from an accelerometer built into a microchip.

A switch is a simple device that makes or breaks a circuit. A switch can perform mainly two functions- ON, by closing its contacts, or fully OFF, by opening its contacts. When contacts are closed, it creates a path for the current to flow, and vice-versa, an open contact will not allow the current to flow. In electrical wiring, switches are most commonly used to operate electric lights, permanently connected appliances or electrical outlets.

In 1884, John Henry Holmes invented the quick break light switch. His technology ensured the internal contacts moved apart quickly enough to deter the electric arching which could be a fire hazard and shorten the switch’s lifespan. This quick break technology is still employed in today’s domestic and industrial light switches.

The most commonly available and used electrical switches in our homes is the one-way switch. But there also exists two-way switch, though not commonly used. In its working, the main difference between them is the number of contacts they each have. The one-way switch has two contacts and the two-way switch has three contacts.

True. Evolution processes illustrate the tension that exists between individuals' efforts to promote change and customers' preferences and habits related to existing (previously adopted) solutions.

Evolution processes do indeed illustrate the tension that exists between individuals trying to bring about change and the preferences and habits of customers who have already adopted existing solutions. This tension can be seen in the constant struggle between innovation and tradition, as well as between individual creativity and the need to conform to established norms and expectations. Ultimately, the success of any new idea or product depends on finding the right balance between these competing forces and striking a chord with customers who are willing to embrace change while still staying true to their own values and preferences.
Evolution is a process that results in changes in the genetic material of a population over time. Evolution reflects the adaptations of organisms to their changing environments and can result in altered genes, novel traits, and new species.

true or false. all else being equal, eccentricity in loading improves the ability of a line weld to support the load.

Answers

False. All else being equal, eccentricity in loading reduces the ability of a line weld to support the load. Eccentricity refers to the deviation of the applied load from the centerline of the weld, which creates a bending moment that can lead to failure or deformation of the weld. A weld that is loaded concentrically, or along its centerline, is better able to support the load without experiencing these detrimental effects.

False. Eccentricity in loading refers to the application of a load that is not centered on the axis of the weld. In general, eccentric loading is not desirable as it creates bending moments on the weld, which can lead to increased stresses and potential failureThe ability of a line weld to support a load is influenced by various factors, including the quality of the weld, the material properties, and the design of the joint. The load capacity of a weld can be improved by proper design, such as increasing the weld size or using stronger materials.Therefore, it cannot be said that eccentricity in loading improves the ability of a line weld to support the load. In fact, it is generally considered detrimental to the weld's ability to support load. Welds are designed to handle axial loading, and eccentric loading can lead to premature failure of the weld. Hence, it is important to avoid eccentric loading whenever possible and ensure that the weld is properly designed and fabricated to handle the intended loads.
False. Eccentricity in loading refers to the application of a load away from the central axis, which can create additional stresses on a line weld. This may reduce the ability of the line weld to support the load effectively, as it could lead to a higher risk of failure under the uneven distribution of stress.

if one wished to operate at a larger current of 8.1 a while maintaining the rod temperature within the safety limit, the convection coefficient would have to be increased by increasing the velocity of the circulating air. what is the recommended convection coefficient for this case?

Answers

Unfortunately, I cannot provide a recommended convection coefficient for this case as the information provided is insufficient to calculate it. However, it is stated that to operate at a larger current of 8.1 A while maintaining the rod temperature within the safety limit, the convection coefficient would have to be increased by increasing the velocity of the circulating air.

This means that increasing the velocity of the air would help in dissipating the heat generated by the larger current and prevent the rod from overheating.It is not possible to provide a specific recommended convection coefficient for this case without additional information about the specific application and operating conditions. The convection coefficient is dependent on a variety of factors, including the geometry of the system, the velocity of the air, and the temperature difference between the rod and the surrounding air.However, in general, increasing the velocity of the circulating air can help to increase the convection coefficient and improve heat transfer from the rod to the surrounding environment. This can help to maintain the rod temperature within a safe operating range while allowing for a larger current of 8.1 A.In practical applications, the recommended convection coefficient may be specified by industry standards or guidelines, or may be determined through experimentation or simulation. It is important to ensure that the convection coefficient is properly calculated and applied to ensure safe and reliable operation of the system.To determine the recommended convection coefficient for operating at a larger current of 8.1 A while maintaining the rod temperature within the safety limit, we need more information about the specific system, materials, and safety limits. However, in general, increasing the velocity of the circulating air can help enhance the convection coefficient, leading to better heat dissipation and keeping the temperature within the desired range.

a parallel rlc circuit contains a resistor r = 1 ω and an inductor l = 2 h. select the value of the capacitor so that the circuit is critically damped

Answers

To design a critically damped parallel RLC circuit with a resistor R = 1Ω and an inductor L = 2H, you need to select the value of the capacitor C according to the following formula: C = 1 / (4 * R * L) Plug in the values for R and L: C = 1 / (4 * 1 * 2) C = 1 / 8 So, you need to select a capacitor with a value of 1/8 F (0.125 F) for the circuit to be critically damped.

To calculate the value of the capacitor required to make the parallel RLC circuit critically damped, we need to use the formula for the damping ratio, which is given by: ζ = R / (2√(L/C)) where R is the resistance, L is the inductance, C is the capacitance, and ζ is the damping ratio. For critically damped behavior, ζ = 1, which means: 1 = R / (2√(L/C)) Substituting the given values of R = 1 Ω and L = 2 H, we get: 1 = 1 / (2√(2/C)) Squaring both sides and rearranging, we get: C = 8/9 F Therefore, the value of the capacitor required to make the parallel RLC circuit critically damped is 8/9 F.

To make a parallel RLC circuit critically damped, the value of the capacitor should be chosen so that the damping factor is equal to 1. In a parallel RLC circuit, the damping factor can be calculated using the formula:

damping factor = R / (2 * √(L * C))

Given that R = 1 Ω and L = 2 H, we can rearrange the formula to find the value of the capacitor (C):

C = (R^2) / (4 * L)

Plugging in the values, we get:

C = (1^2) / (4 * 2) = 1 / 8

A suction line accumulator is used to ensure that liquid refrigerant enters the compressor.True or False

Answers

False. A suction line accumulator is used to ensure that only vapor refrigerant enters the compressor, while any liquid refrigerant is stored in the accumulator until it can evaporate and turn into vapor.
False. A suction line accumulator is used to prevent liquid refrigerant from entering the compressor. Its purpose is to collect and temporarily store any excess liquid refrigerant, allowing only vapor refrigerant to pass through to the compressor.False.

A suction line accumulator is a component used in refrigeration systems to prevent liquid refrigerant from entering the compressor. Its purpose is to collect and store any liquid refrigerant that may be present in the suction line and vaporize it before it reaches the compressor. The accumulator accomplishes this by having a baffle inside the accumulator that separates the liquid refrigerant from the refrigerant vapor. The refrigerant vapor is then allowed to exit the accumulator and continue on to the compressor, while the liquid refrigerant is stored at the bottom of the accumulator until it vaporizes and can also exit.If liquid refrigerant were to enter the compressor, it could cause damage to the compressor due to the compressor being designed to compress vapor refrigerant and not liquid refrigerant. Liquid refrigerant in the compressor could also lead to reduced efficiency and cooling capacity of the refrigeration system.herefore, the correct statement is that a suction line accumulator is used to prevent liquid refrigerant from entering the compressor, not to ensure that it enters the compressor.

Lateral buckling is inhibited by the rigid frame action of the arches and the horizontal elements linking the two arches to each other. This provides stability and support for the structure.

Roll-thru buckling is partly inhibited by the combined effect of the angled suspenders and the deadweight of the roadbed, as well as by the roadbed attaching to the arch at about the quarter points of the arch. This attachment helps distribute the load and prevent buckling. Tension elements in the roadbed provide the horizontal force required to achieve full arch action over the full length of the arches, ensuring stability. Finally, roll-through buckling is also inhibited by the rigid frame action of the arches and the horizontal elements linking the two arches to each other, maintaining the overall structural integrity.

The statement that best describes the buckling mechanisms of an arch bridge is e. roll-through buckling is inhibited by the rigid frame action of the arches and the horizontal elements linking the two arches to each other.

Arch bridges are designed to support loads primarily through axial compression forces. However, they are also susceptible to different types of buckling under certain loading conditions. Roll-through buckling is one of the most critical types of buckling in arch bridges, where the arch rolls or twists laterally due to insufficient lateral bracing, resulting in instability and possible collapse.To inhibit roll-through buckling, arch bridges typically incorporate horizontal elements that link the two arches, creating a rigid frame action that can resist lateral forces. The angled suspenders also provide additional bracing to reduce the lateral displacement of the arches. In contrast, tension elements in the roadbed primarily resist the vertical forces that act on the bridge, such as the weight of the traffic and the weight of the bridge itself.In summary, the rigid frame action of the arches and the horizontal elements linking the two arches together are critical factors that inhibit roll-through buckling in an arch bridge.
