shaft rotation rate

A typical pump has a head that, for a given shaft rotation rate, varies with the flow rate, resulting in a pump performance curve as in Fig. P3.181. Suppose that this pump is 75 percent efficient and is used for the system in Prob. 3.180. Estimate (a) the flow rate, in gal/min, and (b) the horsepower needed to drive the pump

Prob. 3.180

Water at 20°C is pumped at 1500 gal/min from the lower to the upper reservoir, as in Fig. P3.180. Pipe friction losses are approximated by hf ≈ 27V2 /(2g), where V is the

 

average velocity in the pipe. If the pump is 75 percent effi- cient, what horsepower is needed to drive it?
