Question

3. Water is supplied to a town through a gravity main, 0.6m in diameter and 50 km long,
across an undulating ground from the headworks to the service reservoir in the town. The
pipe off-take at the headworks is at a reduced level (RL) +480 m and the maximum water
level of the reservoir is at RL +380 m. The lowest ground level of the mains is at RL
+280 m at a point 25 km from the take-off. It is desired to increase the current supply to
the town by 30%. Determine the distance you would lay a duplicate pipe of the same
diameter. State all assumptions made.
