Suppose the pump of Fig. P1419C is situated between two large water tanks with their free surfaces open to the atmosphere. Explain qualitatively what would happen to the pump performance curve if a valve in the piping system were changed from 100 percent open to 50 percent open, all else being equal. Repeat for the system curve. What would happen to the operating pointwould the volume flow rate at the operating point decrease, increase, or remain the same? Indicate the change on a qualitative plot of H versus V . , and discuss. (Hint: Use the energy equation between the free surface of the upstream tank and the free surface of the downstream tank.)
