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?
