2. Pump flow rate Q=0.025m³/s, the reading of pressure gauge at outlet pipe is Pm=3.237 x 105N/m², the reading of the reading of vacuum gauge at inlet pipe is p=0.394 x 105N/m2, the pressure gauge is 0.8m higher than the vacuum gauge, the diameters of inlet and outlet pipes are 100mm and 75mm respectively. The input power of motor is 12.5kW, and the motor efficiency is 0.95. Calculate pump shaft power, pump effective power, pump efficiency and the total efficiency of the pump unit.
