An acceptance test was conducted on a centrifugal pump having a suction pipe 25.4 cm in diameter and a discharge pipe 12.7 cm in diameter. Flow was 186 m³/hr of clear cold water. Pressure at suction was 114.3 mmHg vac and discharge pressure was 107 kPag at a point 91 cm above the point where the suction pressure was measured. Input to the pump was 15 hp. a. Determine the pump efficiency b. If the pump runs at 1750 rpm, what net flow, head, and brake hp would be developed and required if the pump speed were increased to 3500 rpm? Assume constant efficiency.
