• Water must be pumped from a stream to a water tank several hundred feet (meters) away. The discharge point will be 50 ft (15.3 m) above the stream. The pipeline from the pump to the tank will consist of 340 ft (104 m) of 4-in. (10.2-cm)straight pipe,three standard elbows, and a check valve. The pump will be located 10 ft (3.1 m) above the stream. The suction line will consist of 20 ft (6.1 m) of 4-in. (10.2-cm) hose equipped with a foot valve [equivalent straight pipe length = 70 ft (21.4 m)]. If the required flow is 280 gal/m (1060 //min), find the total head that the pump must overcome. What is the minimum-size M-rated pump required for this system?
