Table$10$: flow under sluice gate results

help to calculate:

$5L=5{10}^{-3}L{m}^3$

$y_1,y_2={10}^{-3}mmm$

$B=0\mathrm{.}076m$

ANALYSIS AND CALCULATIONS

$Q_{\text{a}\text{c}\text{t}\text{u}\text{a}\text{l}}=\frac{y}{t}$

Qexpermit $=\frac{y_2}{y_1}\sqrt[\phantom{2}]{\frac{2}{1+\frac{y^2}{y_1}}}B\sqrt[\phantom{2}]{9y_1^3}$

Froude number: $\frac{y_2}{y_1}\sqrt[\phantom{2}]{\frac{2}{1+\frac{y^2}{y_1}}}$

Froude number: $\frac{y_2}{y_1}\frac{x}{\frac{2}{1+\frac{y^2}{y_1}}}$

$(1.)$ Calculate the actual flow rate

Qactual $=$ Volume

$2-$Calculate the Experimental flow rate. $Q_{\text{e}\text{x}\text{p}}[$Equation $3]3-$ Calculate the upstream Froude number. $[$Equation $4]$

$(4-)$ Graph ${?}^y{?}^2\frac{2}{1}$ versus $Q_{\text{e}\text{x}\text{p}}$ and $Fr$

$5-$ Determine $\frac{y_2}{y_1}$ corresponding to maximum flow. Note that $\frac{y_2}{y_1}$ varies from $0$ to $1.$
