29 REVIEW INNOVATIONS 2. A pipe 977 m long branches into 3 pipes at junction A. The three pipes span 1046 m, 885 m, and 796 m. They come together at junction B and continue as a single pipe for 1224 m. All pipes are 300 mm in size except the shortest one which is 250 mm. The pressure drop between the junctions is 260 kPa. Friction factor "f" can be assumed 0.02 in the entire system. Calculate the rates of flow in the branching pipes.

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
Three pipes of 400 mm, 350 mm and 300 mm diameter are connected in series between two reservoirs with a difference in level of 12 m. The friction factors are 0.024, 0.021 and 0.019 respectively. The lengths are 200 m, 300 m and 250 m respectively. Which of the following statements is TRUE. * The discharge in pipe 1, 2 and 3 are decreasing. The total head loss is equal to the difference in elevation between reservoirs. The head loss in pipes 3 is equal to the sum of losses of pipes 2 and 3.
