Pressure Pressure = Force/Area Units of force per unit area URVISH PI-I
Hydrostatic Pressure Hydrostatic pressure is the pressure in a liquid. The pressure increases as the depth in a liquid increases, due to its weight.
In term of equation, P = ghgh = density in kg/m3 g = acceleration due to gravity (9.8m/s2) h = depth in liquid in m
P = pressure in Pa Manometers

Ionization Gauge Electrodes URVISH PI-I
Ionization Gauge It can be used to measure pressure down to about 2 torr. The gas is ionized with a beam of electrons and the current is measured between two electrodes in the gas. The current is proportional to the number of ions per unit volume, which also proportional to the gas pressure.
