Wohl Parameter (b) Formula:
From: | To: |
Definition: Wohl parameter b is an empirical parameter characteristic to equation obtained from Wohl model of real gas.
Purpose: It helps in describing the behavior of real gases by accounting for molecular volume and intermolecular forces.
The calculator uses the Wohl equation:
Where:
Details: Accurate calculation of Wohl parameters is essential for modeling real gas behavior in chemical engineering and thermodynamics applications.
Tips: Enter all required parameters including reduced and actual values for volume, temperature, and pressure, along with Wohl parameters a and c.
Q1: What are typical units for Wohl parameters?
A: Parameter b typically has units of m³/mol, but depends on the units used for other parameters in the equation.
Q2: How do I obtain reduced parameters?
A: Reduced parameters are calculated by dividing the actual parameter by its critical value (Tc, Pc, Vc).
Q3: When is the Wohl equation most useful?
A: For polar gases and high-pressure conditions where ideal gas law fails.
Q4: Can this calculator handle negative values?
A: No, all input values must be positive numbers.
Q5: What's the accuracy of this calculation?
A: Accuracy depends on the precision of input parameters and the applicability of the Wohl equation to your specific gas.
