Question (1): (18 marks) (a) State the steady flow energy equation in the form of energy per unit mass, with clear descriptions and SI units of all parameters in the equation Write down in the format as shown below. Like: A=B+ cx torý where A: mass ckg) B: . (b (b) A pump draws fresh water from a lake to a pool on the hilltop at a rate of 150 kg/min, as shown in the figure. The water enters the pool from a height of z= 110 m (above the water free surface of the lake). The overall efficiency of the motor-pump unit is 75% and the motor consumes electricity at a rate of 4.2 kW. If the irreversible head loss in the piping is 8 m, find (1) the rate of energy loss in the piping (in unit of W), and (i) the velocity of the water at the pipe outlet at the hilltop. Pump N IK
