Two reservoirs are interconnected with a piping network as shown in Figure 3. Water is drawn off at B, C and D. Take only frictional head losses into account (the Fanning friction factors for each pipe are provided in table 1) and use the Hardy-Cross method to calculate the flow rate in each pipe. Show your calculations thoroughly for at least problem initialization (iteration 0) and the first iteration. Thereafter all other iterations may be in the form of a table. List the final flow rates.

A new water supply main is being planned for a new city of 2 million population and average per capita water demand of 300 litres per day. The water source is located 50 km from the newly planned city at similar elevation as the city. Water is proposed to be conveyed using two number of 100 cm diameter cast iron pipeline in parallel. Assume water density of 1,000 kg/m3 and viscosity of 1.0 x 10-3 kg/m-s. Determine the following: a. The total head loss (in m) during this conveyance of water in each pipeline. Use Colebrook equation to calculate frictional factor. b.
