Two identical pumps in parallel configuration will be used to draw water from Reservoir A (water elevation 772') up to Reservoir B (water elevation -878'). The pipe will be 4,860 long, 2' diameter, with a Hazen-Williams coefficient of 100. Assume minor losses are negligible. The pump performance curve from thee manufacturer for one of these pumps is shown below. Determine the operation point for the two pumps in parallel by plotting below.

A pump that is 80% efficient pumps water from the lower tank to the upper tank at a flow rate of 0.01 m/s through 70 meters of 10-cm diameter pipe. In this system there are two regular, screwed 90 degree elbows and a fully open screwed angle valve. Assume the reservoir exits and entrances are sharp. The friction factor,f, of the pipe is 0.02. What horsepower pump is needed to achieve this flow rate? Use: Pwater = 998 kg/m2; Mwater...
