What horsepower must be supplied to the pump in order

Reference no: EM13548172

A pump of 80% efficiency lifts water from one large open tank to another; the difference in water surface elevations is 20 feet. The pipe is relatively smooth (f = 0.0122), and has 3 elbows, each with a loss coefficient of 2/3. The pipe is 4-inches in diameter and 40 feet long. The kinematic viscosity of water is 10-5 ft2/sec. What horsepower must be supplied to the pump in order to convey 2 CFS through the system? (Kent = .5) Assume a submerged exit.

a). 7.8HP

b). 17.2HP

c). 26.5HP

d). 34.6HP
