Water at $20C$ is being drained from an open tank through a cast iron pipe $0\mathrm{.}6$ m

diameter and $30$ m long. The surface of water in the tank is at atmospheric

pressure and at an elevation of $46\mathrm{.}9$ m $,$ and the pipe discharges to the atmosphere

at an elevation $30$ m $.$ Neglecting minor losses due to fittings, valve, etc. determine

the volumetric flow rate of water leaving the pipe. You may consider the flow

to in fully turbulent region with friction factor $f0\mathrm{.}0042.$ Feel free to use Moody

chart or explicit relation for estimating the Re number.
