Gas Density and Specific Volume Calculator
The Gas Density and Specific Volume Calculator calculates the density and specific volume of gas based on a modified version of the Ideal Gas Law:
where:
P is the absolute pressure of the gas,
V is the volume of the gas,
n is the number of moles of gas,
T is the absolute temperature of the gas,
R is the universal gas constant
The Ideal Gas Law assumes the existence of a gas with no volume and no interactions with other molecules. Therefore,
the Compressibility Factor (Z) can be used
for a slight alteration to the ideal gas law to account for real gas behavior. Therefore the equation used for these
calculations is:
where:
P is the absolute pressure of the gas,
V is the volume of the gas,
n is the number of moles of gas,
T is the absolute temperature of the gas,
R is the universal gas constant
Z is the gas compressibility factor
This equation is sometimes referred to as the Non-Ideal Gas Law
This calculator has been scaled to use English units for temperature and pressure. Molecular weights for acetylene,
air, ammonia, argon, carbon dioxide, carbon monoxide, chlorine, hydrogen, natural gas, nitrogen, oxygen, propane and
steam are all provided. |
