Q$1(25$ pt$).$ Liquid toluene $(867\frac{kg}{m_3})$ is stored in a tank at $93\mathrm{.}2g.$ A small fitting $($diameter $=$

$0\mathrm{.}25cm)$ for QC sampling is accidentally sheared off leaving a rough hole in the tank. Calculate

the discharge rate $(Q\frac{m_{mg}}{s})$ and velocity $(u\frac{m}{s})$ from the tank if the ambient pressure is $1$

atm for both a rough and smooth hole. Hint: A rough hole $(C_0=0\mathrm{.}61)$ would flow less quickly

than a smooth hole $(C_0=1).$
