Refer to the “composite performance chart” for a Goulds 3x4-10centrifugal pump operating at 1750 rpm. It shows the pump performance curve for 5 differentimpeller sizes, but also shows the HP required, efficiency, and NPSH required at differentoperating points.Describe the performance of this pump, using an 8 inch impeller and a required flow rate of175 gpm. Give head available, power required (BHP), efficiency, and NPSH req’d.
What is the water horsepower (WHP)?
Q Consider the following data relating toperformance of a centrifugal pump:speed 1200 rpm, flow rate 30 L/s, head 20 m, and power 5 kW. If the speed of the pump is increased to 1500 rpm, assuming the efficiency isunaltered, Find the new flow rate and head.
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.
