Dry air at a temperature of 300 K, total pressure of 1 atm, and velocity of 0.5 m/s blows
parallel to the length of a pool of liquid water maintained at 278 K. The length of the pool is 10 m
and the width is 4 m. At 278 K, the vapor pressure of water is 1620 Pa. What is the evaporation
rate of water from the pool?

1. Air at a pressure of 101 kPa and temperature of 288 K enters an axial compressor stage with a velocity of 170 m/s. There are no guide vanes, so the air enters in the axial direction only. When traveling through the rotor, the air turns 15 degrees. This means the angle of the relative velocity with respect to the axis is 15 degrees greater when entering the rotor than when it leaves. The rotor spins at 8000 rpm and...
