Question
(a)
A pump draws water (50°F) from a reservoir, where the water-surface elevation is 520
ft and forces the water through a pipe 5000 ft long and 1 ft in diameter. This pipe then
discharges the water into a reservoir with water-surface elevation of 620 ft. The flow rate is
7.85 ft/s and the head loss in the pipe is given by
hi
= 0.01
where, Land D is the length and diameter of the pipe respectively; Vis the velocity.
Determine the head supplied by the pump and the power supplied to the flow. Also draw the
Hydraulic Gradient Line (HGL) and Energy Gradient Line (EGL) for the system. Assume that
the pipe is horizontal and is 510 ft in elevation. Given, viscosity of water at 50°F is 62.4 lbf/ft'.
