Question $3.$: The figure given below shows the profile of a $10-$m$-$wide rectangular channel. Hydraulic jump occurs between Section $(1)$ and Section $(2)$ of the rectangular channel. The water depth and flow velocity before the hydraulic jump are $0\mathrm{.}8m$ and $7\frac{m}{s},$ respectively. Accordingly,

a$)$ Determine the Froude Number before the hydraulic jump and then classify the flow.

b$)$ Calculate the water depth and the Froude Number after the hydraulic jump.

c$)$ Determine the head loss due to the hydraulic jump.
