a)What volume of air at atmospheric pressure is required to fill a 14 L diving air tank at a pressure of 1.45x10^7 N/m²? b) if sea level consumes 13.5 L of air per minute, how long will the air contained in the above tank last? c) How long will the air contained in this tank last at a depth of 10 m where the pressure has increased by 1 atm? Suppose consumption is the same as at sea level. "
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.
