Problem 5
Consider a three-reservoir problem with the following characteristics.
L₁ = 95 m
L₂ = 125 m
L3 = 180 m
Z₁ = 25 m
Z₂ = 115 m
z3 = 85 m
(a) All three pipes are constructed of 28 cm, unfinished concrete (e = 1 mm). If water at 20 ºC
flows through the pipes, compute the steady flow rate in each pipe (magnitude and
direction).
(b) Reduce the diameter of all the pipe to 15 cm, unfinished concrete (€ = 1 mm) and show that
the flow rates distribute in nearly the same manner but are about 5.2 times lower. Explain
why.
