Question 2 A water pump driven by an 800 W electric

Question 2 A water pump driven by an 800 W electric motor is used to pump water from the ground level to a tank at the rate of 20000 l/hour. Water is being discharged into the tank at 10 meters above the ground; this is the maximum rise this pump can achieve. The water and the ambient temperatures are both 10 C. The inlet and outlet pipe diameters for the pump are both 8 cm, respectively. Determine: (1) The average inlet linear flow velocity of the water; (6 marks) 2) Assuming the efficiency of the electric motor is 95%, calculate the efficiency of the motor-pump unit; to marks) 3) The pressure difference between the inlet and the outlet of the pump. (6 marks)
