You were told not to stand so close to a rapidly moving train because you might get sucked under it. What do you think will likely happen to you? Select one: The moving train could actually suck anybody closer to it. The moving train could be out of its way and will hit you. Greater pressure behind you will push you toward the moving train. Greater pressure between you and the train will pull you toward the train.
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.
