PRESSURE AND BOUYANCY
-
PRESSURE
GAS PRESSURE
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.

ATMOSHPERIC GAS PRESSURE
Atmospheric pressure, also known as barometric pressure (after the barometer), is the pressure within the atmosphere of Earth.
-
FLUID PRESSURE
Fluid pressure is the pressure at a point within a fluid arising due to the weight of the fluid. The pressure in fluids can be calculated using the following relation. The density of the fluid can be calculated by dividing the mass of the fluid in consideration with the volume of fluid taken.
-
LIQUID PRESSURE
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.
-
Pressure due to the weight of a liquid of constant density is given by 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, and g is the acceleration due to gravity.
SOLID PRESSURE
-
The equation for pressure is P = F/A. Pressure can be measured for a solid is pushing on a solid, but the case of a solid pushing on a liquid or gas requires that the fluid be confined in a container. The force can also be created by the weight of an object.
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. The units of length and width are metres.
