7.82 Water flows from the reservoir on the left to the reservoir
on the right at a rate of 16 cfs. The formula for the head losses
in the pipes is h₁ = 0.02(L/D)(V²/2g). What elevation in the left
reservoir is required to produce this flow? Also carefully sketch
the HGL and the EGL for the system. Note: Assume the head-loss
formula can be used for the smaller pipe as well as for the larger
pipe. Assume α = 1.0 at all locations.
