Brandon is stuck on a barren island surrounded by sharks. He needs to build a boat to leave , but he doesn’t believe in shapes other than cubes. More unfortunately, he only has lead as material to make his box boat. Brandon and the lead box boat have a combined mass of 500kg. What is the buoyant force that is necessary for the boat to float? How big then must the boat be?
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.
