Two reservoirs are connected using the piping network shown in the figure. The pipes are commercial steel. Water is to be pumped using a pump (efficiency = 70%) that draws 8 kW of electric power from the mains. Ignore minor losses. Determine the flow rate through each pipe and the total flow between the reservoirs. Start with a friction factor of 0.02 for all pipes and use the Haaland equation to calculate updated friction factors. Ignore the length of the pipe between Reservoir 1 and the pump, pump and the junction, and the junction and Reservoir 2. Iterate until you have convergence or 3 iterations (whichever comes first) Look at Example 10-10 in the textbook to get an idea of how to solve this type of problem.

The Figure below (Figure 3) shows a pipe system with a valve and two reservoirs
QUESTION3 The Figure below (Figure 3) shows a pipe system with a valve and two reservoirs. A pump transports a constant flow rate of Q = 0.1 m3/s of water from reservoir A to reservoir B. At four sections the pipe has bends and the roughness of the pipe is ks = 1.5 mm. The pipe has a diameter D = 34 cm and a total length L = 500 m. The water level in reservoir B is Δh=4.67 m above...
