a rectangular solid has mass 10.0 kg and dimensions width 12.0 cm, length 10.0 cm and height 10.0 cm and density of 8333.3 kg/m^3. The solid is dipped in the water such that its top is 5.00 cm under the surface. What is the pressure on the bottom? What is the pressure difference from bottom to top? What is the weight of the displaced fluid? What is the spring scale reading? how do your answers change if the top is 10 cm under the surface?
Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.
