2. The suction pipe of a pump rises at a slope of 3 vertical in 4 along the pipe which is 12 cm in diameter. The pipe is 7.2 m long; its lower end being just below the water surface in the reservoir. For design reasons, it is desirable that pressure at inlet to the pump Pump 4/3 shall fall to more than 75 kPa below atmospheric pressure. Neglecting friction, determine the maximum discharge that the pump may deliver. Take atmospheric Suction pipe pressure as 101.32 kPa. F.W.S. Reservoir/sump 2. 7.2 m
