The diagram below shows a pipe network system. Two connecting reservoirs, 1 and 2, have water level elevations of 150 feet and 30 feet above datum, respectively. This network consists of a 8- inch diameter pipe (Pipe A) of length 1200 feet, connected to a two pipes in parallel, Pipe B (800 feet long with a diameter of 6 inches) and Pipe C (900 feet in length with a 4-inch diameter). The parallel branch then connects back to a single pipe, Pipe D, which is 500 feet long and has a diameter of 6 inches. All pipes are made of concrete, but the roughness varies. This leads to varying friction coefficient values for each pipe, see table below. FIND THE VELOCITIES AND FLOW RATES IN EACH PIPE.

2. You're designing a stilling basin and you need to know the minimum length of that basin and also how much energy loss will be achieved before flow is released into the downstream channel. Given the basin width is 10-feet, the flow rate is 240 CFS, the upstream froude number is found from hydraulic modeling to be 4.0. Solve the following: • Minimum length of the stilling basin. • Energy loss within the stilling basin (Calculate both energy loss in feet and in tons). • The depth of water being released outside of the stilling basin. • The Froude Number being released from the Stilling Basin. • Look at USBR Design of Small Dams and Write a paragraph (4-5 sentences) of the recommended stilling basin you would propose for the hydraulic scenario.
