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.
An open tank holds a liquid with a specific gravity of 1 .45. The liquid has a vertical height of 250 inches. How much head pressure ( in inches of water column) does this liquid exert (show work)
- Specific gravity of an object is defines as the ratio of density of an object to density of water.
specific gravity of object = ......................1
- specific gravity of water = 1
- density of water, dw = 1000 kg/m3
