The total pressure force of a square plate is 25 kN, placed vertically in water so that the center of the plate is 1.5 m below the free surface. Determine the size of the plate and the depth of center of pressure. The above square plate is taken out of the water which weighs 370.5 N in air and 180.3 N in water of specific gravity 0.99. Find the volume and specific gravity of the square plate. Draw a neat sketch.
1. ATectangular plate 1 m wide by 2 m long is immersed in water of density 1000
kg/m3. The shorter side is parallel to the water surface and 0.5 m below it. The
longer side is inclined at 60° to the vertical. Calculate the magnitude, direction and
location of the force acting on one side of the plate due to water pressure.
An open cubic tank of side length 2 m is completely filled with water. If the surface of the water and the outside of the tank are subject to atmospheric pressure, what are the hydrostatic forces acting on:
Each side of the tank?
The base of the tank?
