Question
Water is to be pumped through 1500 ft of pipe from the lower to upper reservoir at a rate of
4 ft'/s, as shown in Figure below. The pipe is cast iron of diameter 8 inch. The pump is 80%
efficient.
(a) Find the velocity and Reynolds number of flow through pipe.
(b) Find the head loss due to friction, h in ft.
(c) Compute the pump head, h, in ft and the pump power needed, Ppump in horse power
(hp).
Given: Density of water, pwater = 1.94 slug/ft'; Viscosity of water, u = 2.05 x 10° slug/ft.s;
Friction factor from Moody Chart, f= 0.021.
Draw sketch and show all calculations.
