(CLO-2, PLO-2, C-3) Being a water supply design engineer, propose an optimum solution for the following situation of a pipe network analysis: Attach a google map of your hometown area. ► Distribute the whole area in 3 pipe network loops (a sample is shown in Fig). Propose the best position of the overhead water tank (volume and height). The capacity of the tank must be calculated based on the total members of the community (Attach detailed calculation, considering 6 persons in one house with 100 gallons per capita per day (GPCD)). The point of flow (say Q1) into the pipe network must be selected near the water tank. ▸ Select the best pipe material and find the pipe roughness. Select the pipe diameter by yourself. Assume all the pipes are at the same elevation. To find: • Calculate the volume of the tank and select the elevation of the overhead water tank. Calculate the pressure head at the inlet of the pipe (say point a in Fig.) • • Find the flow rate for each pipe in the network. • Find the pressure head at each pipe node (say points a, b, c....) ● Find Reynolds number for each pipe. ● Find friction factor for each pipe section. ● Find major head loss in each pipe length (neglect minor losses if the pipe is sufficiently long). ● Find velocity in each pipe. . In the end, discuss the effect of water tank elevation, roughness, diameter and discharge on pressure variation at different nodes (try changing the above parameters and discuss the change in the pressure head).
