From your prior analysis of pumping requirements for a water circulating system, you have determined that a pump capable of delivering 500 gpm at a pressure of 60 psi is required. If a motor operating at 1800 rpm is chosen to drive the pump, which is 70% efficient, determine:

(a) The required horsepower rating of the motor.

(b) The required torque rating of the motor.

(c) The diameter of the impeller that should be used in the pump. (d) What color the pump should be painted.
