What is Meant by Compressibility Factor?

The ideal gas law is an equation that can be used to generalize the behavior of an ideal gas.

This equation, however, can only be used in specified circumstances and for gasses. To account for the behavior of real gasses, this equation was modified. This was accomplished by using a dimensionless entity called the compressibility factor, Z. The ideal gas equation for gas with volume V and n number of moles at pressure P and temperature T with gas constant R is expressed mathematically as follows:

P * V = n * R * T

This is transformed into a compressibility factor equation, which includes the compressibility factor Z:

Z = P * V / n * R * T

The compressibility factor is used to calculate the difference between real-world and ideal-world thermodynamic parameters. The ratio of a gas's actual volume to its ideal volume for a particular temperature and pressure is referred to as the compressibility factor. In terms of mathematics, this is:

Z = Vactual / Videal

What is the Procedure for Using the Compressibility Factor Calculator?

To compute the compressibility factor Z, follow the procedures below.

Step 1: Enter P for the gas pressure.

Step 2: Enter V for the gas volume.

Step 3: Enter the mole quantity of the material, n.

Step 4: Put the universal gas constant, R. The universal gas constant should be set at its default value of 8.314 8.314 J⋅KΓü╗¹⋅molΓü╗¹. In the FPS unit system, the value is 10.73164 [psi ft3]/[lbm mol °R].

Step 5: Put in the gas's temperature, T.

Step 6: The calculator will now return the compressibility factor value using the compressibility factor equation.

FAQs on Compressibility Factor Calculator

1. How do I calculate the compressibility factor?

Step 1: Divide the number of moles by the universal gas constant and the temperature of the gas.

Step 2: Divide the previous product by the pressure.

Step 3: To calculate the compressibility factor, multiply the product by the volume of gas.

2. What is the compression factor Z?

The gas deviation factor, often known as the compressibility factor Z, is the modifying factor for actual gases. It's the ratio of a gas's volume at a given temperature and pressure to the volume it would occupy if it were an ideal gas at the same temperature and pressure.

3. What is the compressibility factor Z in physical significance?

The departure of real gas qualities from ideal gas behaviour is represented by the compressibility factor Z. It's used to convert ideal gas qualities to real gas properties.
