Refresher - HYDRAULICS Quiz 3PROBLEM 1-3:
In the figure shown, reservoir A is the source of water supply and is at elevation 150 m, B is
the junction at elevation 91.46 m, C is a town at elevation 30.49 m. with 25000 inhabitants,
D is another town at elevation 15.24 m. with a population of 30000 inhabitants. Length
AB = 15,240 m, BC is 9150 m, BD = 6100 m. Determine the size of the pipes if the
consumption is 150 liters per capita per day. For the pipes, friction factor f = 0.02.
El. 150 m
➀ Determine the required diameter of pipe AB. A
➁ Determine the required diameter of pipe BC.
➂ Determine the required diameter of pipe BD.
