3" ID Pipe 2) (pump) 2" ID 25 ft Absorber Pipe 15 ft 5 ft storage tank The pump shown here is used to lift a process liquid of density 1.93 slug / ft' from a storage tank, and discharge it at a rate of 0.75 cubic feet per second into the top of an absorber. The inlet to the absorber is located 25 feet above the free surface of the liquid in the storage tank, and the pump inlet is located at an elevation of I5 feet above that of the free surface. You can assume that the absorber operates at atmospheric pressure. A 2" ID pipe leads from the storage tank to the pump, while the pipe from the pump to the top of the absorber is of ID 3". You can assume the losses in the 2" ID pipe to be 4 velocity heads, and the losses in the 3" ID pipe to be 5 velocity heads. Assuming the pump is 85% efficient, calculate the BHP (Brake Horse Power) of the pump.
