common small boat for use in quiet streams and lakes has a flat bottom and is approximately rectangular in shape like the smaller ones in this photo. For fishing they would be about 5.4 m long, 1.3 meters across at the bottom, and have a hull mass of 215 kg (475 lb weight) if made of aluminum. Along a side they might have a depth of 0.6 meter (about two feet) from the upper edge to the bottom, though many small ones are not that deep. What is the maximum load that could be put into the boat in addition to its own mass that it could still float without being swamped by water over the 0.6 m sides?
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.
