Temperature of Real Gas Formula:
From: | To: |
Definition: This calculator determines the actual temperature of a real gas using the Wohl parameter c, reduced temperature, and critical properties.
Purpose: It helps in thermodynamic calculations for real gases where ideal gas assumptions don't apply.
The calculator uses the formula:
Where:
Explanation: The formula accounts for non-ideal behavior of real gases through the Wohl parameter and critical properties.
Details: Correct temperature determination is crucial for process design, safety calculations, and understanding gas behavior under various conditions.
Tips: Enter the reduced temperature, Wohl parameter c, critical pressure in Pascals, and critical molar volume in m³/mol. All values must be positive.
Q1: What is reduced temperature?
A: Reduced temperature is the ratio of the actual temperature to the critical temperature of the substance.
Q2: How do I find the Wohl parameter c?
A: Wohl parameters are typically determined experimentally or from thermodynamic tables for specific substances.
Q3: What are typical values for critical properties?
A: These vary by substance. For example, water has Pc ≈ 22.06 MPa and V'c ≈ 0.056 m³/kmol.
Q4: Why does this formula include critical properties?
A: Critical properties help characterize the non-ideal behavior of real gases near their critical points.
Q5: Can this be used for all gases?
A: This is specific to the Wohl equation of state. Other equations may require different parameters.
