Problem 4 (10 points) A pipeline with two pumps (Pump A and Pump B) in series delivers water between two tanks with a total static head of 50 ft. The pipeline is 8 inches in diameter and 5000 ft in length, with a Darcy- Weisbach friction factor f = 0.025. The total minor head loss coefficient Ek 20. The characteristics of the two pumps are shown in the following table. Determine (a) the operating conditions of head and discharge, (b)...

Operating in series are two reversible heat pumps. Heat transfer
gives energy to the first cycle from a cold reservoir at 105 K and
rejects energy by heat transfer to a reservoir at an intermediate
temperature T greater than 105 K. The second cycle receives energy
by heat transfer from the reservoir at T and rejects energy by heat
transfer to a higher-temperature reservoir at 1200 K. If the heat
pump cycles have the same co-efficient of performance, calculate:
Low...
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.
