1. What is the Reynold's number for water flowing in a 24-inch circular pipe at a velocity of 6.21 ft/s? Is the flow laminar or turbulent? 2. A reservoir of water is connected to 8-inch-diameter pipe 50 feet long and discharging freely. The water surface elevation of the reservoir is 410.0, and the elevation of the center of the pipe at its discharge end is 372.5. Neglecting friction, determine the velocity, v, and discharge, Q, at the end of the pipe.

From reservoir A water is supplied by a pipe that is 12 inches in diameter and 1000 ft long. At point D it is divided into two branches. One 6 inch-diameter, 2000-ft-long pipe connects to reservoir B and another 12 inch-diameter, 1500-ft- long pipe connects to reservoir C. The surface elevations at A, B, C, and D are 120 ft, 80 ft, 40 ft, and 60 ft respectively. Determine the flow in each pipe. Take f = 0.007 for all pipes and PD/γ is 20.5 ft.

Water resources engineering Please refer to the attached image. The new cat iron pipe carrying a flow of 0.3 ft3/s becomes divided at point B and rejoins at point C. The elevation at the reservior surface is 1300 feet. The elevation at point D is 560 feet. The pipe diameters and lengths are listed below. What is the pressure at point D? Neglect minor losses. Use the Darcy-Weisbach approach and assume fully turbulent flow. Verify this assumption for one of the pipes. If the assumption is not perfect, iteration is not necessary, just verify and comment.
