![]() ![]() (The weight-density of water is 62.4 pounds per Find the fluid force exerted against the vertically submerged flat surface depicted in the diagram. $$ W= 62.4 \int_$$ītw, the correct lb to kg conversion is 2.2 lb/kg and kg to ton(US) 907 kg/ton(US). Find the fluid force on the vertical side of the tank (see figure below), where the dimensions are given in feet. $$ dW= 62.4 \times y \times \pi x^2 dy \times y$$Īnd since we are raising the water from the point $y = -2$ to $y = 0$ to make it appear that the water reaches the top of tank: Substituting this newly-found $dF$ to $dW$ described in the figure above: The force $F$ is equal to specific volume of liquid $\times$ distance $\times$ area or in differential form: $$dF = w \times h \times dA$$Īs seen in the figure above: $$dF = 62.4 \times y \times \pi x^2 dy$$ ![]() I'm getting the differential work $dW$: $$dW = dF \times x$$ $ The work done by a variable force from $x= a$ to $x = b$ is: $$W = \int_a ^b F(x) dx$$ I do know that $Work = Force \times distance. Hydraulic force on the plate Adc where, A area of the submerged portion specific weight of water and dc is the depth of center of gravity of the. Find the work done in pumping the water to the top of the tank. ![]() I was studying for some exams when I encountered this question:Ī hemispherical tank of radius 6 feet is filled with water to a depth of 4 feet. ![]()
