Decomposition is the process of breaking the Work Breakdown Structure (WBS) into smaller and smaller deliverables. This process is also sometimes referred to as value engineering or detailed specifications. By decomposing the WBS into smaller pieces, it becomes easier to assign tasks, assign costs, and plan out timelines.

The decomposition process begins by taking the major deliverables of the project and breaking them down into smaller tasks. From there, each task is further broken down into even more specific tasks. This process is repeated until all tasks have been broken down into their smallest components.

The purpose of decomposition is to create a well-defined scope of the project so that it can be managed in an efficient manner. It allows managers to easily identify the resources, cost, and timeline of each task, as well as provide a way to evaluate the progress of each task. It also allows for better control of the overall project.

Decomposition is a critical part of the project management process, as it ensures the project is organized and defined. This ultimately leads to an overall better result for the customer.

The correct answer is To determine the minimum size of the THHN copper feeder tap conductor, we need to calculate the ampacity of the tap conductor based on the 75-degree Celsius column of the NEC table 310.16.

First, we need to find the equivalent ampacity of the 225A main breaker panelboard. Since it is a continuous load, we have to multiply it by 1.25. So, 225A x 1.25 = 281.25A. Next, we need to find the percentage of the feeder ampacity required for the tap conductor. The NEC table 310.16 allows tap conductors to have an ampacity not less than one-third of the rating of the overcurrent device protecting the feeder. Therefore, 1200A/3 = 400A. Finally, we can calculate the minimum size THHN copper feeder tap conductor using the following formula: Minimum conductor ampacity = (281.25A - 180A) + 180A = 281.25A Minimum conductor ampacity = 281.25A / 0.8 (derating factor) = 351.56A From the NEC table 310.16, the minimum size THHN copper conductor with an ampacity of 351.56A is 2/0 AWG. Therefore, the minimum size THHN copper feeder tap conductor that can be used is 2/0 AWG.

The criteria for matching streams above the pinch for designing heat exchangers is to make sure that the hot stream and the cold stream are both having the same temperature. The criteria for matching streams below the pinch is to make sure that the hot stream and the cold stream have the same heat capacity.

These criteria are needed to ensure that there is an efficient heat exchange, meaning that the hot stream will give up most of its heat to the cold stream. In order for this to occur, it is essential that the temperature and heat capacity of the two streams are similar. If the temperatures of the hot and cold streams are too different, the efficiency of the heat exchange will be greatly reduced.

The Isentropic efficiency of the compressor Let's consider the given parameters; Initial conditions: T1 = 290 kP1 = 90 kPa Final conditions: T2 = 480 kP2 = 390 kPa The isentropic efficiency of the compressor can be calculated using the following formula:ηs = (h2s - h1) / (h2 - h1)Whereηs = Isentropic efficiency of the compressorh1 = Enthalpy at the inlet of the compressorh2 = Enthalpy at the outlet of the compressorh2s = Isentropic enthalpy at the outlet of the compressor.

Now let's calculate the enthalpies; From the given conditions, we can find out the state point of the air at the inlet of the compressor using the steam tables: At P1 = 90 kPa, T1 = 290 K Using the steam tables, we find out h1 = 315.83 kJ/kg Similarly, we can find out the state point of the air at the outlet of the compressor using the steam tables: At P2 = 390 kPa, T2 = 480 K Using the steam tables, we find out h2 = 421.45 kJ/kg Now, let's calculate the isentropic enthalpy at the outlet of the compressor: Using the steam tables, we can find out the state point of the air at the outlet of the compressor if it were isentropic.

The 10-stage pipeline's clock cycles would take 1.5ns to finish on average, which is 1.5ns longer than the 5-stage pipeline's.

To calculate the clock cycle time of a 5-stage pipeline and a 10-stage pipeline, we need to consider the time required for each stage and the pipeline register delay.

For a 5-stage pipeline with a longest stage of 0.6ns and a pipeline register delay of 0.1ns, the total clock cycle time would be:

Clock cycle time = longest stage time + pipeline register delay = 0.6ns + 0.1ns = 0.7ns

This means that each clock cycle in the pipeline would take 0.7ns to complete.

For a 10-stage pipeline with the same longest stage time and pipeline register delay, the total clock cycle time would be:

Clock cycle time = longest stage time + (pipeline register delay x (number of pipeline stages - 1)) = 0.6ns + (0.1ns x 9) = 1.5ns

This means that each clock cycle in the 10-stage pipeline would take 1.5ns to complete, which is longer than the 5-stage pipeline due to the additional pipeline stages.

It is worth noting that while longer pipelines can potentially increase performance by allowing for higher clock rates, they can also increase the risk of pipeline hazards and decrease overall efficiency due to increased latency and complexity.

This is about projectiles and the time taken to reach point P, 40 meters above the ground, is approximately 4.04 seconds.

To solve this problem, we can use the kinematic equation that relates displacement, initial velocity, final velocity, acceleration, and time:

y = vi*t + (1/2)at^2

where y is the displacement (in meters), vi is the initial velocity (in meters per second), a is the acceleration (in meters per second squared), and t is the time (in seconds).

At the top of the building, the body has an initial velocity of 50 m/s, which is purely vertical. The acceleration due to gravity is -9.8 m/s^2 (negative because it acts downward).

When the body reaches point P, its displacement from the top of the building is 120 m - 40 m = 80 m.

So, we can use the above equation to find the time taken to reach point P:

80 = 50t + (1/2)(-9.8)*t²

Simplifying and solving for t, we get:

A 0.85-hp motor is required by a ducted fan to produce a 24-in stream of air having a velocity of 40 ft/s then the efficiency of the fan is 20.47.

The efficiency of a ducted fan is determined by the ratio of power output (the kinetic energy of the air stream) to the power input (the power of the motor). In this case, the power output can be calculated using the following equation:
Power Output = 0.5 x density of air (in kg per meter cube) x velocity of air (in m/s) x cross-sectional area of air (in meter square) x ( square of velocity of air (in m/s))
Since the velocity of the air is 40 ft/s (which is equivalent to 12.19 m/s), the power output can be calculated as follows:
Power Output = 0.5 x 1.2 kg/m3 x 12.19 m/s x (24 in x 24 in) x (12.19 m/s x 12.19 m/s) = 13024.7 Watts
The power input of the motor can be calculated using the following equation:
Power Input = 0.85 x 746 = 634.1 Watts
Therefore, the efficiency of the fan can be calculated using the following equation:

Impact, ballistic, and creep ripples are all types of surface features that can occur on materials subjected to different types of stresses.

Impact ripples are formed when a material is struck by a projectile or another object. Ballistic ripples are similar but are specifically formed by high-velocity projectiles. Creep ripples, on the other hand, are formed when a material is subjected to a constant stress over a long period of time, causing it to slowly deform.

The length of these ripples relative to their heights can vary depending on the specific material and conditions. However, in general, the ripples tend to have a relatively short wavelength compared to their height.

In comparison, aerodynamic and hydrodynamic ripples are formed by the flow of air or water over a surface. These ripples tend to have a much longer wavelength compared to their height, with the length-to-height ratio typically ranging from several to tens of thousands. This is because the fluid flow over the surface is generally much smoother and less abrupt than the stresses that cause impact, ballistic, and creep ripples.

The given statement "When solving the impact problems, we should always assume that during an impact between two bodies, there is no permanent deformation in the bodies" is False and  there is usually some amount of permanent deformation during an impact when semi-truck collides head-on with a mini car.

The statement is False because In reality, there is usually some amount of permanent deformation that occurs during an impact, especially if the impact is severe. However, in many cases, the amount of deformation may be negligible or can be ignored for simplicity in calculations.Therefore the statement is False.

If a semi-truck collides head-on with a mini car then According to Newton's Third Law of Motion, every action has an equal and opposite reaction. Therefore, both the semi-truck and the mini car will exert equal force on each other during a head-on collision. The force experienced by each vehicle will depend on factors such as their mass, speed, and the duration of the impact. However, it is likely that the semi-truck, being much larger and heavier than the mini car, will experience less of a change in velocity than the mini car and therefore will exert more force on the smaller vehicle.
