If the force on the tympanic membrane (eardrum) increases by about 1.50 N above the force from atmospheric pressure, the membrane can be damaged. What is the force from atmospheric pressure on the membrane assuming it is circular and typically 8.20 x10-3 m in diameter? What is the maximum force on the ear drum before it is damaged? What is the maximum pressure on the ear drum before it is damaged? When diving in the ocean, at what depth could damage to your eardrum start to occur? Take the density of seawater to be equal 1.03×103 kg/m3.
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.
