Question:

Using the result from Problem 13.26, describe how the performance of the pump changes if the system head increases by 15 percent.

In Problem

For the 2 × 3 - 10 centrifugal pump performance curve shown in Fig. 13.28, at what head will the pump having an 8-in impeller operate at its highest efficiency? List the pump€™s capacity, power required, efficiency, and the required NPSH at that head.

Impeller diameter 10 in 3136-41-46 140 2x3- 10 3500 RPM 450 151 54 56 57 58 58.7 400 9 in 120 58 57 350 100 S in 300 50
