. Two reservoirs containing water (density of 1.94 slug/ft3 and molecular viscosity of 2.09 x 10-5 slug/ft/s) are connected by circular pipes whose diameters are 1 in and 2 in, respectively. Change in pipe diameter occurs abruptly 20 ft from the reservoir. Also, the entrance and exit regions of pipes are sharp edged. The average. surface roughness height is e = 1.5 x 10-4 ft for both pipes. The water surface of the reservoir on the left is 45 ft higher than that of the other reservoir. Flows at and are nearly at rest, but the flow inside both pipes is not. Considering minor losses as well, estimate the volume flow rate of water at 20° C. The minor loss coefficients are 0.5 for a sharp pipe entrance, 0.56 for a sudden pipe expansion in diameter, and 1.0 for a pipe exit. Use the standard value for the gravitational acceleration g.
