A reservoir supplies water to four recipients. Each recipient demand a fixed discharge of 20 l/s (liter per second). Determine the diameter at the exits, so the exact flow rate is provided. The supplier pipe diameter (which is different from the exit diameters)is 10 inches. The distance from the reservoir to the closest recipient is 200 m. Then the other 3 recipients are separated by 200 m. The reservoir free water surface is 5m above the recipients, which are located at the same topographic level. Friction losses along the pipe are modeled with Darcy Weisbach formula with ks=0.0005 (asphalted cast iron). Singular losses at the entrance to the main pipe has a loss factor of K=1.Singular losses at the exits of the pipe (at the recipients) have a loss factor K=2.Hint: Note that you already know the velocities and Reynolds numbers of the flow along the pipe, so you don't need to iterate on Moody abacus (just use it a single time per pipe section). 2. Civil Engineer Aquino Wells (SDSU alumni) is revising exercise 2 of Lab 2. The exercise consist of two tanks receiving water from a major tank A located above.Each tank serve two areas of the city. The engineer thinks it is unfair that the area close to tank C receives much less water supply. The engineer proposes the following solutions to make the water supply of the city more equitative. Hint: Assume singular losses are negligible. For all the calculations use Ch=120, as we did in Lab 2.
