A 170-m long pipeline, composed of two pipes connected in series, discharges freely at a point 40 m below the water level at intake. The pipe projects into the reservoir. The first 100 m is 25 cm in diameter, and the remaining 70 m is 15 cm in diameter. Assuming that f-0.05 for both pipes, (a) find the rate of flow. If the junction of the two sizes of pipe is 25 m below the imtake water-surface level, find the pressure head just above C and just below C, where C denotes the point of junction. Assume a sudden contraction at C. Use k-0.8 for entrance, 0.24 for sudden contraction and 1.0 for exit.
