A rectangular sluice gate with a width of $2\mathrm{.}17$ ft is placed inside a small dam to control the flow releases from the dam reservoir.

It is closed when it touches the reservoir bottom and opens by rising vertically.

Determine the flow rate through the gate if the opening of the gate is $0\mathrm{.}56$ ft and the water level in the reservoir is $7\mathrm{.}5$ ft$,$ to the nearest $0\mathrm{.}1$ cfs$.$
