Questions #2
The discharge of the pipe system shown is 0.85 M/sec. The length of pipes 1, 2, 3, 4 and 5 are
1000 m, 500 m ,600 m, 800 m and 700 m, respectively.
Pipes 2, 3 and 4 are laid parallel and drawn from
pipe 1 and discharge into pipe 5. The diameters of
pipes 1, 2, 3 and 5 are 90 cm, 50 cm, 40 cm and 75
cm respectively. The total head loss in the pipe is 10 m. Assuming f=0.02.
