Water from an open reservoir a at 8m elevation is drawn by a motor driven pump to an open reservoir b at 70 m elevation. the inside diameter of the suction pipe is 200 mm and 150 mm for the discharge pipe. the suction line has a loss of head 3 times that of the velocity head in the in the 200 mm pipe. the discharge line has a loss of head 20 times that of the head in the discharge pipeline. the pump centreline is at 4 m. overall efficiency of the system is 78% for a discharge rate of 10 li/s, find the power input to the motor and the pressure gages reading installed just at the outlet and inlet of the pump in kpag
