An open tank contains a 0.120-m layer of oil floating on water that is 0.250m deep. The density of the oil is 600kg/m^3. a. What is the gauge pressure at the oil-water interface? b. What is the gauge pressure at the bottom of the tank? c. If the top of the tank is open to air (uncovered), what is the absolute pressure at the bottom of the tank? d. If the tank is covered, what will happen to the gauge pressure in interface and bottom of the container?
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.
