15.27
![15.26 A flow of 1 m/s is divided into three parallel cast-iron pipes of diameters 500, 250, and
400 mm and lengths 400 m, 100 m, and 250 m, respectively. Determine the head loss and
flow through each pipe.
15.27 Two reservoirs having a difference of 40 ft in water elevations are connected by a 1.5-mile-
long cast-iron pipe of 1 ft diameter. A second pipe 1.5 ft in diameter and one-half mile in
length is laid alongside the first one for the last half-mile. How is the discharge affected?
15.28 For the pipe system shown in Fig. P15.28, determine the rate of flow. Disregard the minor

At point D it is divided into two branches. A 50-cm-diameter, 600-m-long pipe (f=0.024)
connects to reservoir B while a 60-cm-diameter, 1200-m-long pipe (f= 0.02)connects to
reservoir C. The surface elevations at A, B, C, and D are 30 m, 20 m, 10 m, and 25 m,
respectively. Determine the flow in each pipe.
15.29 From reservoir A, water is supplied by a 100-cm-diameter, 3000-m-long pipe (f= 0.015).
