A sharp$-$edge orifice with corner taps is to be used to measure water flow rate $(60F)$ in a

horizontal $2-$in pipe $(2\mathrm{.}067$in$.$ ID$).$ The maximum flow is expected to be about $7$ cfm $($cubic

feet per minute$).$ Determine the diameter of the orifice if a maximum pressure difference of $2$

psi is acceptable. $($Answer must match to $3$ decimal places$).$
