4. Estimate the buoyant force that you are experiencing, right now. You must do this quantitatively, so please use estimations about your size and shape that are reasonable for humans. Justify your choices diagrammatically. The density of air in your room is approximately 1.29 kg/m³ and you may ignore any variations due to temperature. Hint: pick a simple shape, or shapes, to represent you. (Vsphere = 4/3 tr", Veyldinder = Tr*h, and V cube = lwh)

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.
