Compressibility Formula
The following formula is used to calculate the compressibility factor of a gas.
Z = P * V / (n * R * T)
- Where Z is the compressibility factor
- P is the pressure (pascals)
- V is the volume (m^3)
- n is the number of moles
- R is the gas constant (8.31432*10^3)
- T is the temperature (K)
Compressibility Definition
Compressibility, in this case, the compressibility factor, is defined as the rate at which a material changes in volume under a force or pressure.
Compressibility Example
How to calculate compressibility?
- First, determine the pressure.
Measure the pressure acting on the material.
- Next, determine the volume of the material.
Calculate the total volume of the gas under that pressure.
- Next, determine the number of moles.
Calculate the total number of moles of the gas.
- Next, determine the temperature.
Calculate or measure the temperature of the gas.
- Finally, calculate the compressibility factor.
Calculate the compressibility factor using the equation above.
FAQ
Compressibility is a measure of a material or gasses ability to compress under a certain force or pressure.
This factor is a ratio of the pressure and volume to the moles and temperature of a gas. It represents the compressibility of the gas.
Compressibility is calculated using the ideal gas formula and re-arranging the values to create a ratio.
