The area of the top side of a piece of sheet metal is given below. The sheet metal is submerged horizontally in 8 feet of water. Find the fluid force on the top side. (The weight-density of water is 62.4 pounds per cubic foot.) 3 square feet

Given that,

Height at which the metal sheet is submerge

H = 8ft

Fluid Force at the top side with area sheet of 3ft², A = 3ft²

Weight density of water

w = ρg = 62.4 lb/ft³

The fluid pressure can be calculated using

P = ρgh

But we are already give the weight density ρg

Then,

P = w•h

P = 62.4 * 8

P = 499.2 lb/ft²

The force from top side?

We can calculate the force using the formula for pressure

Pressure = Force / area

P = F/A

F = P*A

F = 499.2 * 3

F = 1497.6 lbs
