Question: Develop an empirical equation that represents the net positive suction head required (m) as a function of capacity (m3/h) for a Bell & Gossett Series

Develop an empirical equation that represents the net positive suction head required (m) as a function of capacity (m3/h) for a Bell & Gossett Series e-1531 2.5BB pump with a 9-inch impeller operating at 3550 rpm. The equation should be valid from 50 to 180 m3/h. Estimate the percent accuracy in the calculated NPSHr from the correlated equation by developing a deviation plot.
