A test on centrifugal pump operating at 3237 rpm showed a total head of 39 ft at a capacity of 900 gpm. Estimate the total head and capacity of the pump if it were operated at 1750 rpm. Assume normal operation at point of maximum efficiency in each case.
A manufacturing company uses a 100 bar hydraulic power system which supplies 10 liter/minute of oilflow. The shaft speed is 1500 RPM and the nominal displacement is 8 cm3/revolution. The theoreticaldrive torque is 11.4 Nm. If the electric motor driving the pump has an efficiency of 95%,a. Name in detail all 27 hydraulic power components as illustrated in the above figure.b. Calculate the volumetric efficiency, the fluid and shaft power, the overall efficiency of the pump.
You and your workmate are choosing pumps for your design. You've already decided which centrifugal pump you will use. The next thing you would think about this time would be the shape of it's impeller blades. The impeller in your design would have a revolution of 565 rpm, will have a volume flow rate of 11.7 gals per min and will (discharge) head of 2222 cm. Your coworker said that axial flow pump is your choice. Would you agree? Why or why not? Prove it.

An existing pump is used to pump water with the following data at BEP: D = 2.15 in, N = 1784 rpm, ρ = 998 kg/m3, Q = 18 gpm, H = 4.2 ft. A larger pump is to be designed based from the existing one to be used for pumping slurry (ρ = 1220 kg/m3) such that its best efficiency point occurs as close as possible to a volume flow rate of 48 gpm and at a net head of 15 ft. Calculate the new pump diameter in inches. Round off your final answer to 3 decimal places.
