4. = Water at 20deg Celsius is to be pumped from a reservoir (ZA = 5 m) to another reservoir at a higher elevation (ZA 13 m) through two 36-m-long pipes connected in parallel, as shown in the figure below. The pipes are made of commercial steel, and the diameters of the two pipes are 4 and 8 cm. Water is to be pumped by a 70 percent efficient motor-pump combination that draws 8 kW of electric power during operation. The minor losses and the head loss in pipes that connect the parallel pipes to the two reservoirs are considered to be negligible. Determine the total flow rate between the reservoirs and the flow rate through each of the parallel pipes. You can assume the friction factor is 0.02 in both pipes. ZA = 5 m Control L₁ = 36 m D₁ = 4 cm volume -boundary Pump D₂ = 8 cm L₂ = 36 m ZB = 13 m
