4.34 Laboratory experiments indicate that a centrifugal pump operating with a 7-in. impeller at 1150 rpm delivers 60 gpm of water at 60°F with a head of 27 ft. At this condition, the pump draws 1.8 hp. The affinity laws are now used to predict the performance of this pump at 1750 rpm. Conduct a parametric study to determine the capacity, head, and power draw of the pump at this new operating speed as function of the water temperature ranging from 40°F to 190°F. Comment on the results.
