EXAMPLE $8-6$ Turbulent Draining from a Pool

Reconsider the draining pool example, Example S$-1$ The flow rate was very low, so the pool owner uses a larger diameter hose $($Fig$.8-35).$ The new hose has inner diameter $D=2\mathrm{.}00cm$ and average roughness height $=0\mathrm{.}0020cm.$ All other parameters remain the same as the previous problem, including the length of the hose. Calculate the volume flow rate in liters per minute $($LPM$)$ at the start of draining.
