Consider a human head as a sphere of diameter 15.0 cm. Find the total force exerted on it due to a standard pressure of 1.0 atm = 1.01325 x 105 Pa = 1.01325 x 105 N/m2. What if suppose this sphere is submerged to a depth of 1.0 km from the ocean surface whose water is essentially uniform and of the same density as that of water at room temperature and pressure. What is the total force on the sphere. Note: Disregard the variation of pressure along the surface of the sphere.Required to answer. Single choice.
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.
