Definition: Molar Volume of Real Gas is the volume occupied by one mole of a real gas at a specific temperature and pressure.
Purpose: This calculator determines the actual molar volume of a real gas using the Wohl equation and reduced parameters.
The calculator uses the formula:
Where:
Explanation: The formula relates the actual molar volume to reduced parameters and the Wohl parameter c.
Details: Accurate molar volume calculations are essential for gas storage, transportation, and industrial process design.
Tips: Enter all required parameters. Ensure temperature is in Kelvin and pressure in Pascals. All values must be positive.
Q1: What are reduced parameters?
A: Reduced parameters are dimensionless quantities representing the ratio of actual conditions to critical conditions.
Q2: How do I obtain Wohl parameter c?
A: Wohl parameter c is typically determined experimentally or from critical properties of the gas.
Q3: What's the difference between ideal and real gas molar volume?
A: Real gases deviate from ideal behavior due to intermolecular forces and molecular volume, especially at high pressures and low temperatures.
Q4: Can this calculator be used for any gas?
A: Yes, as long as you have the correct parameters for the specific gas.
Q5: What are typical units for molar volume?
A: Molar volume is typically expressed in cubic meters per mole (m³/mol) or liters per mole (L/mol).
