2 A 32m high down comar-tank exib high down comar-tank system operates at loobar. IF the quality of the stream 0.5 what will be ther me driving Pressure. Assume S to be 1.4.

Solve fast with Proper Equation. 1. A centrifugal pump delivers 2.5 cfs of water against a head of 25 ft at 1500 rpm and requires 10 hp. If the speed is reduced to 1250 rpm calculate the power , assuming the same efficiency. Select one: a. 17.3 kW b. 13.7 kW c. 5.8 kW d. 8.5 kW

7. Use the pump map attached, Suppose I want to pump water at 120 gpm against a head of 10 m. a. What size impeller should I use... note it is between two .. do I want the larger or the smaller and why. b. With this impeller, you can read the hp required and the pump efficiency.. report them. c. What input head is required (NPSH)? d. If I use the largest impeller at 120 gpm it should be clear I will generate extra "head" or pressure. What could I do to handle this extra head .. ie to not deliver too much pressure to my system?

can you please find the solution
