Determine the force due to hydrostatic pressure acting on the hinge of the gate shown. The fluid density is d and the width of the elliptical gate (out of the page) is 6H.
(I have attached the picture provided)
The answer is supposed to be: 21(pi)dg(H^3)/8
This solution contains an annotated force body diagram and shows step-by-step calculations and explanations to determine the force due to the hydrostatic pressure using fluid density and width.
