An orifice meter is used to measure the flow rate of $\mathrm{CCl}_{4}$ in a $2 \mathrm{in}$. sch 40 pipe. The orifice diameter is 1.25 in., and a mercury ( $\mathrm{SG}=13.6)$ manometer attached to the pipe taps across the orifice reads $1 / 2$ in. Calculate the volumetric flow rate of $\mathrm{CCl}_{4}$ in $\mathrm{ft}^{3} / \mathrm{s}\left(\mathrm{SG}\right.$ of $\left.\mathrm{CCl}_{4}=1.6\right)$. What is the permanent energy loss in the flow due to the presence of the orifice in $\mathrm{ft}_{\mathrm{f}} \mathrm{lb}_{\mathrm{f}} / \mathrm{lb}_{\mathrm{m}}$ ? Express this also as a total overall "unrecovered" pressure loss in psi.
