Water is flowing from a higher reservoir to a lower reservoir (Fig. 4), with an elevation difference of 30 m. The total length of the galvanized iron pipeline is 80 m. The pipeline contains three fully open globe valves and two 90-degree standard elbows. The reservoirs are open to atmospheric pressure.
Determine the smallest standard pipe size that can be used to deliver water at a rate of 2.65 m3/min.
Loss coefficients for entrance = 0.5, each elbow = 0.3, each globe valve = 6, exit = 1. Assume the density of water is 1000 kg/m3 and the viscosity of water is 10-3 Pa.s.
H = 30m
