Problem $7$

A rectangular channel with a width of $1$ meter is constructed. It was observed that the flow depth and velocity of water after undergoing a hydraulic jump are measured to be $1\mathrm{.}1$ meter and $1\mathrm{.}75\frac{m}{s},$ respectively.

$18.$ Determine the flow depth before the jump $($m$).$
