Please help with this. Liquid flowing at high speed in a wide, horizontal open channel under some conditions can undergo a hydraulic jump, as shown. The flows entering and leaving the jump may be considered uniform with hydrostatic pressure distributions $($see Example $4\mathrm{.}7,$ this means you'll have a resultant force, $F_R=p_{c}A,$ acting on each side of the CV$).$

For this problem, determine the depth of the water, $D_2,$ with respect to the other variables in the system $($you will show that $D_2=D_1\frac{\sqrt[\phantom{2}]{1+8\frac{V_1^2}{g}{D}_1}-1}{2}).$
