Figure $4\mathrm{.}4$: The gate with opening.

Given the difference between the two levels in Figure $4\mathrm{.}4(H,2\mathrm{.}9m,$ and the diameter $m$ of the orifice, determine the flowrate through the orifice. Also Determine the flowrate from the orifice in case you did not have any water on the right $($thus water flows from the left to the atmosphere$).$ The level $h$ is equal to $7\mathrm{.}8m,$ and the $C_c$ is equal to $0\mathrm{.}56.$
