Given a constant speed pump, calculate the change in flow, pressure, and power with a change in impeller diameter. Given the following... D1= 10-inch impeller diameter Flow (q1) is 200 GPM Pressure (TDH1) is 150 ft Speed is 3600 RPM Power (BHP1) is 50 hp Determine... q2, TDH, and BHP when impeller diameter is increased to 12 inches at the same speed (3600 RPM)
