A pump is used to transfer ethanol (SG = 0.787) in a processing plant from a storage tank to a mixing tank. If the total head loss due to friction and the pipe fittings in the system is 1.5m, and the pipe is 1 ½ in S40 stainless pipe, determine the power (kW) of the pump. The velocity at the pipe exit is 5 m/s, and the storage tank is open to the atmosphere. Assume the efficiency of the pump is 75%.

Atmospheric air has a temperature (dry bulb) of 80° f and a wet bulb temperature of 60° f when the barometric pressure is 14.696 psia. determine the specific humidity, grains/lb dry air. a. 11.4 c. 55.8 d. 22.5 b. 44.1

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
