Pure liquid benzene (C6H6) at 290 K flows as a thin film downthe outside of a vertical, 0. 08 m diameter cylinder at a flow rate4 kg/hr. Dry air at 290 K and 1 atm flows perpendicular to thecylinder at a velocity of 4 m/s. The liquid benzene exerts a vaporpressure of 8100 Pa. Determine the length of the cylinder if theentire outer surface of the cylinder is used for the evaporatingprocess, and all of the benzene flowing down the cylinderevaporate. Assume that surrounding air serves as an infinite sinkfor mass transfer
