4.2.11. A pump is needed to convey 8 cfs of water at 68°F through a 130-ft-long horizontal, ductile iron pipeline to a pressurized tank. The pump and pipeline are installed at an elevation of 10 ft, the water surface elevation in the receiving tank is 20 ft, and the pressure at the top of the tank is 32.3 psi. The pipe has a 15-in.-diameter on the suction side of the pump and a 12-in.-diameter on the discharge side of the pump. If the pump delivers 111 ft of head, determine the pressure head on the discharge side of the pump (in psi) and whether cavitation is a concern on the suction side of the pump? Sketch the system and draw the HGL and EGL.

Transcribed Image Text:4.2.11. A pump is needed to convey 8 cfs of water at 68°F through a 130-ft-long horizontal, ductile iron
pipeline to a pressurized tank. The pump and pipeline are installed at an elevation of 10 ft, the water
surface elevation in the receiving tank is 20 ft, and the pressure at the top of the tank is 32.3 psi. The
pipe has a 15-in.-diameter on the suction side of the pump and a 12-in.-diameter on the discharge
side of the pump. If the pump delivers 111 ft of head, determine the pressure head on the discharge
side of the pump (in psi) and whether cavitation is a concern on the suction side of the pump?
Sketch the system and draw the HGL and EGL.
