An engineer has designed a system in which a positive-displacement pump is used to pump water from an atmosphere tank into a pressurized tank operating at 150 psig. A control valve is installed between the pump discharge and the pressurized tank. With the pump running at a constant speed and stroke length, 350 gpm of water is pumped when the control valve is wide open and the pump discharge pressure is 200 psig.
(a) If the control valve is pinched back to 60 percent open, determine the water flow rate.

A centrifugal pump is used to pump water at 77ºF from a reservoir whose surface is 20 ft above the centerline of the pump inlet. The Pipe System consists of 67.5 ft of PVC pipe with a 1.2 in ID and negligible average internal roughness height. The length of the pipe from the bottom of the lower tank to the pump inlet is 12 ft. There are several minor losses in the pipe: an acute edge entry (KL = 0.5),...
