Water must be pumped from a stream to a water tank 500 ft (153 m) away. The discharge point will be 30 ft (9.2 m) above the stream. The pipeline from the pump to the tank will consist of 550 ft (168 m) of 4-in. (10.2-

cm) straight pipe, four standard elbows, two 45° elbows, and a gate valve. The pump will be located 10 ft (3.1 m)

above the stream. The suction line will consist of 25 ft

(7.5 m) of 4-in. (10.2-cm) hose equipped with a strainer

[equivalent straight pipe length = 5 ft (1.5 m)]. If the required flow is 300 gal/m (1136 ( /min), find the total head that the pump must overcome. What is the minimum-

size M-rated pump required for this system?
