Homework Consider the arrangement shown: a = 8 m, b = 6 m, h = 11 m and 0 =20 ,the gate has a width of 0.80 m into the paper. The block has a specific gravity of 7.0 and it's totally immersed in oil (S = 0.82). Calculate 1) The hydrostatic force acting on the gate (in kN). 2) The vertical distance between the line of action of the hydrostatic force "center of pressure" and water surface (in m). 3) The volume of the block required to start opening the gate. (in m). h Rope Water a Hinge Gate Block S=7.0 Oil S=0.82
