Oil with specific gravity of 0.88 flows through a pipe which changes from 6 in. at section A to 18 in. at section B. Section A is 12 ft lower than B and the pressures are 13.2 psi and 8.75 psi, respectively. If the flow rate is 5.17 cfs, determine (a) The velocity (ft/s) at section A, (b) The velocity (ft/s) at section B, (c) The head lost (ft) between the two points, and (d) The direction of flow. Is it from A to B or B to A?
