4.33 A centrifugal pump is being tested with water at 60°F. The pump is operating at 1150 rpm and has a 7-in. impeller. Performance test results indicate that the pump delivers 80 gpm at a head of 32 ft with a power draw of 2.5 hp. Using the affinity laws, predict what the pump capacity, head, and power draw would be if the operational speed was increased to 1800 rpm and the fluid

a. Is water at 130°F

b. Is toluene at 130°F
