PRESSURE AND BOUYANCY
-
PRESSURE
GAS PRESSURE
ATMOSPHERIC GAS PRESSURE
-
The standard atmosphere is a unit of pressure defined as 101,325 Pa , which is equivalent to 760 mm Hg, 29.9212 inches Hg, or 14.696 psi.
TRAPPED GAS PRESSURE
Gas trapped in the intestines can be incredibly uncomfortable. It may cause sharp pain, cramping, swelling, tightness, and even bloating. Most people pass gas between 13 and 21 times a day. When gas is blocked from escaping, diarrhea or constipation may be responsible.
-
LIQUID PRESSURE
p=ρgh p = ρ g h , where p is the pressure, h is the depth of the liquid, ρ is the density of the liquid
-
The pressure in a liquid is different at different depths. Pressure increases as the depth increases. The pressure in a liquid is due to the weight of the column of water above. Since the particles in a liquid are tightly packed, this pressure acts in all directions.
SOLID PRESSURE
-
Pressure is the force per unit area. This means that the pressure a solid object exerts on another solid surface is its weight in newtons divided by its area in square metres.
-
FLUID PRESSURE
Fluid pressure is a measurement of the force per unit area on a object in the fluid or on the surface of a closed container. This pressure can be caused by gravity, acceleration, or by forces outside a closed container. Since a fluid has no definite shape, its pressure applies in all directions
