Imagine two blocks as shown in Figure 10A-1. The two blocks, with the same size bases, are resting on the horizontal surface of a table. Each block pushes down on the underlying surface with a force (weight) that is ______ the downward force exerted by the other block. a.different from b.equal to c.twice By definition, pressure is the amount of force acting on an area of surface. Pressure is calculated by dividing the force exerted on a surface by the area over which the force is applied. The blocks weigh the same and their bases have the same area, so the two blocks exert ______ pressure on the underlying surface. a.half the b.the same c.twice the
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.
