Problem1 A two stage centrifugal pump is designed to discharge water at a total head of 70 m with an overall efficiency of 0.76. The pump runs at 2331.6 rpm. The actual head developed (per stage) is 65% of the theoretical head. The flow at the inlet is pure radial. The impeller at the exit has a diameter of D2 = 0.219 m and a width of b, = 0.0216 m. The outlet blade angle is ß2 = 28°. Determine: 1. The flow rate of the pump. 2. The output power of the two stage centrifugal pump. p = 1000kg/m³ g = 9.81 m²/s Take
