Situation 3. A reservoir A, the free water surface of which is
at an elevation of 275 m, supplies water to reservoirs B and C with
water surfaces at 180 m and 150 m elevation respectively. From A to
junction D there is a common pipe 300 mm diameter and 16 km long.
The pipe from D to B is 200 mm diameter and 9.5 km long while that
from D to C is 150 mm diameter and 8 km long. Neglect losses other
than pipe friction and taking f = 0.01 for all pipes.
3.a. Calculate the rates of flow at A in (m³/s)
3.b. Calculate the rates of flow at B in (m³/s)
3.c. Calculate the rates of flow at C in (m³/s)
