The flow rate of water through the pipe system shown in the figure is 30 lit/s under the total head loss of 10m. Assume C = 120 for all pipes. Determine the diameter of line C in mm.

Two pipes A and B are connected in parallel between two points M and N as shown in figure. Pipe A is 80 mm diameter, 900 m long and its friction factor is 0.015. Pipe B is of 100 mm diameter, 700 m long and its friction factor is 0.018. A total discharge of 0.030 m³/s is entering the parallel pipes through the division at M. Calculate the discharge in the two pipes A and B. M = 0.015 A fA 80 mm dia, 900 m 100 mm dia, 700 m B fB = = 0.018 N

The pipe connection shown has a series parallel connection. The rate of flow in the pipe 1 is 300 liters per sec. Assuming equal values of f = 0.02 for all pipes. Compute the discharge of pipeline 2 in cu.m per sec. Compute the discharge of pipeline 3 in cu.m per sec. Compute the discharge of pipeline 4 in cu.m per sec.
