Where \(w\) is the liquid's weight-density per volume unit.īelow are weight-densities for common fluids in pounds per cubic foot. The pressure on an object at depth \(h\) in a liquid is At 30 feet below sea level the pressure is 30 pounds per square inch. ![]() At sea level the atmospheric pressure is 15 pounds per square inch. It is measured in pounds per square inch or kilograms per square centimeter. Pressure is the force on a body's surface area. What is the fluid force on the window? (Density of water sea water is 64.At sea level 15 pound presses on the one inch square and one kilogram presses on the one centimeter square. What is the fluid force on the gate when the top of the gate is 4 meters below the surface of the water? 4 m 8 m 5 m 6 mĪ circular observation window on a marine science ship has a radius of 1 foot, and the center of the window is 8 feet below water level. The tank is completely full of water.Ī vertical gate in a dam has the shape of an isosceles trapezoid 8 meters across the top and 6 meters across the bottom, with a height of 5 meters, as shown below. 507 Find the fluid force exerted on the bottom of the container.įind the fluid force on a rectangular metal sheet measuring 2 feet by 3 feet that is submerged in 5 feet of water.įind the fluid force on the vertical side of a rectangular tank with dimensions 5 ft.
