$4\mathrm{.}4\mathrm{.}7.$ A three$-$loop water distribution system is depicted in Figure. The demands on the system are currently at junctions $C(6\mathrm{.}00cfs),D(10\mathrm{.}0cfs),$ and $E(12\mathrm{.}0cfs).$ 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.
