Reduced Molar Volume Formula:
From: | To: |
Definition: Reduced Molar Volume for P-R Method of a fluid is computed from the ideal gas law at the substance's critical pressure and temperature per mole.
Purpose: It helps in comparing the properties of gases at different conditions by normalizing them relative to their critical properties.
The calculator uses the formula:
Where:
Explanation: The molar volume is divided by four times the Wohl parameter b to obtain the reduced molar volume.
Details: Reduced properties are essential in thermodynamics for creating generalized correlations that can be applied to many substances.
Tips: Enter the molar volume of real gas in m³ and the Wohl parameter b. All values must be > 0.
Q1: What is the Wohl parameter b?
A: Wohl parameter b is an empirical parameter characteristic to equation obtained from Wohl model of real gas.
Q2: What units should be used for input values?
A: Molar volume should be in cubic meters (m³) and Wohl parameter b is dimensionless.
Q3: What does the reduced molar volume represent?
A: It represents the molar volume normalized by the critical properties of the substance.
Q4: Can this calculator be used for any gas?
A: Yes, as long as you have the correct Wohl parameter b for the specific gas.
Q5: What's the typical range for reduced molar volume?
A: The value varies depending on conditions, but it's typically around 1 near the critical point.
