Please choose one of the questions between 4.4.10 or 4.4.7 4.4.10. Using EPANET, determine the flow rate and head loss in each cast-iron pipe in the network shown in Figure. The demands on the system are at junctions C (0.030 m³/s), D (0.250 m³/s), and H (0.120 m³/s). Water enters at junctions A (0.100 m³/s) and F (0.300 m³/s). The lengths and diameters of the pipes are provided in the table below. As with all computer programs, the results should be checked for accuracy. Spot check a few junctions to see if there is mass balance. Check one or two loops to see if the energy balances.

A three-loop water distribution system is depicted in Figure. The demands on the system are currently at junctions C (6.00 cfs), D (10.0 cfs), and E (12.0 cfs). Water enters the system at junction A from a storage tank with a pressure of 40 psi. Using the pipe network data in the table below, calculate the flow rate in each pipe (initial estimated flows are provided). Also determine if the pressure at any junction drops below 30 psi, the pressure required by the customers. Use EPANET for this question.

How to know your submitted files will work? Before you submit, make copies of all your final EPANET files in a new folder on your computer and run EPANET from this new folder. Conduct a check to ensure that the program can run without any trouble.
