Liquid toluene $(867$ kg$/$m$3)$ is stored in a tank at $93\mathrm{.}2$ psig. A small fitting $($diameter $=0\mathrm{.}25$ cm$)$ for QC sampling is accidentally sheared off leaving a rough hole in the tank. Calculate the discharge rate $($Qm kg$/$s$)$ and velocity $($u m$/$s$)$ from the tank if the ambient pressure is $1$ atm for both a rough and smooth hole. Hint: A rough hole $($Co $=0\mathrm{.}61)$ would flow less quickly than a smooth hole $($Co $=1).$
