Water is flowing in Four side-by-side pipes. The discharge through each pipe is 1.2 m³/sec and the water depth in each pipe is 0.609D. The Manning's n and the bed slope of each pipe are 0.016 and (1:1000), respectively. After the development, the total discharge is expected to increase by 13%, and the engineers have decided to replace the Four pipes by a trapezoidal channel. The new channel with a non- cohesive material having a particle size of 0.61 mm with the same bed slope of the pipes. Assume the channel bed width is twice the water depth, and the side angle of the channel is 60°. 1- Determine the diameter of the pipes. 2- Design the cross section of the new channel and what are your comments and suggestions about the hydraulic flow in the designed channel? 3- If a hump is placed in the bottom of the designed channel, Estimate the hump height which will cause the crest flow to be critical.

1. Determine the discharge rate through three parallel corrugated metal pipe culverts shown in the sketch below (Use the outlet control). The 48-inch diameter culverts have a Manning, n value of 0.024. The culverts are 80 ft long, laid on a slope of 0.04, and have a projecting inlet and outlet. The culvert inlet bottom elevation is 302 ft with a head water elevation of 308.2 ft and a tailwater elevation of 302 ft. Use Ke = 0.8, Ko = 1.0.

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.
