Problem $5$: Water at $21$C flows from the tank through the $25$ mm diameter galvanized iron pipe. If the faucet $($gate valve$)$ is fully opened, determine the volumetric discharge at A$.$ Include the minor losses of the flush entrance, the two elbows, and the gate valve. $($L$1$ and L$2$ are $0\mathrm{.}6$ m in length. L$3$ and L$4$ are $1\mathrm{.}2$ m in length.$)$
