Crater Lake in Oregon is the deepest lake in the United States, with a maximum depth of 655 m. The density of freshwater is 1.00 ✕ 103 kg/m3. (a) If the air pressure above the lake, which has a surface altitude of 1800 m, is 8.00 ✕ 104 Pa, what is the absolute pressure at the bottom of the lake? (b) What is the force of the lake's water on each window of a submarine near the lake bottom if each of its circular windows has an area of 118 cm2? (Enter the magnitude.)
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.
