A centrifugal exhauster is takin in dry air from a room where the temperature is 60 °F and the barometer is normal. The axis of the horizontal discharge pipe (12 inch inside diameter) is 1 ft. above that of the intake pipe (16 in inside diameter). The air in the discharge pipe is at a pressure of 1.2 in of water above normal barometric pressure. The air then flows through a meter and the rate flow is found to be 2.5 lb/s. The power input to the drive shaft of the exhausted is 8 hp. Neglecting the heat exchange with the room, calculate the temperature (in °F) of the air in the discharge pipe?
