Assuming a L-shaped gate having its height H, length L and width B is connected by a hinge as shown in figure, the force F required to hold the gate closed is calculated as below.

■ Forces due to water pressure
▷ Horizontal force
Fh = (1/2)*ρ*g*H^2*W
▷ Vertical force
Fv = ρ*g*H*L*W

■ Moment at the hinge by the forces above
M = (1/3)*H*Fh + (1/2)*L*Fv

■ Force to make a resistent moment required
F*H = M
F = M/H = ((1/3)*H*Fh + (1/2)*L*Fv)/H
= (1/6)*ρ*g*H^2*W + (1/2)*ρ*g*L^2*W
= (1/2)*ρ*g*((1/3)*H^2 + L^2)*W

*** 참고문헌[References] ***

F = (1/2)*ρ*g*((1/3)*H^2 + L^2)*W
