A US Navy nuclear submarine (mass m = 10,000,000 kg) is cruising under the Arctic ice sheet at a depth of 200 m. (a) If the submarine is maintaining constant depth while cruising, what is the size of the buoyant force on it? (b) Assuming that the density of seawater is 1023 kg/m 3 , what is the volume of the submarine? (c) What is the water pressure at the cruising depth of the submarine (remember that the pressure increase due to the depth has to be added to the pressure at the surface, which is the atmospheric pressure P ATM = 101,000 Pa)? JUST THIS PART NEEDS TO BE ANSWERED PLEASE: (d) This submarine is fitted with a circular window of area A = 0.1 m 2 . Find the net force on this window (i.e., force from outside minus force from the inside) assuming that the air pressure inside the submarine is equal to P ATM .
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.
