Figure $3\mathrm{.}5$: The cilindrical gate.

Figure $3\mathrm{.}5$ shows a schematic of a cilindrical gate with diameter $D$ of $1\mathrm{.}1m,$ and a width $L$

$($the length in the direction perpendicular to this page$)$ of $1\mathrm{.}0m.$ The gate is hinged in A$,$

and when the water $($kinematic viscosity $1\mathrm{.}1*{10}^{-6}{m}^2{s}^{-1})$ level upstream reaches the depth

$h=4\mathrm{.}8m$ the gate opens by turning around A$.$ With the given data:

The total magnitude of the water thrust : N

The angle of action from the horizontal plane : Degrees

The weight of the gate : N
