of 4.5 m, to reservoir B, with static discharge head of 15 m. the pipe in the suction line is a 6” nominal diameter, sch. 40, and 80 m long. The pipe in the discharge side is a 4” nominal diameter, schedule 40, and 150 m long. The fittings and valves installed in the suction line are one-foot valve, one standard elbow, and one gate valve: and in the discharge line are one check valve, one gate valve, and two standard elbows. Assuming an absolute roughness of 0.24 mm for a cast iron pipe, and an absolute viscosity of water of 0.01002 Poise. Neglecting the head losses in the foot valve and at the exit in the discharge reservoir. Determine the pump brake power if the pump efficiency is 82
A pump is required to draw 50 lps of water (SG = 0.988) from reservoir A, with static suction
lift of 4.5 m, to reservoir B, with static discharge head of 15 m. the pipe in the suction line is a 6”
nominal diameter, sch. 40, and 80 m long. The pipe in the discharge side is a 4” nominal
diameter, schedule 40, and 150 m long. The fittings and valves installed in the suction line are
one-foot valve, one standard elbow, and one gate valve: and in the discharge line are one check
valve, one gate valve, and two standard elbows. Assuming an absolute roughness of 0.24 mm
for a cast iron pipe, and an absolute viscosity of water of 0.01002 Poise. Neglecting the head
losses in the foot valve and at the exit in the discharge reservoir. Determine the pump brake
power if the pump efficiency is 82
