Temperature of Real Gas Formula:
From: | To: |
Definition: This calculator determines the actual temperature of a real gas using the Wohl equation parameters, reduced temperature, and critical properties.
Purpose: It helps in thermodynamic calculations for real gases where ideal gas assumptions don't apply, particularly in chemical engineering and physical chemistry applications.
The calculator uses the formula:
Where:
Explanation: The formula relates the actual temperature to reduced temperature and critical parameters through the Wohl equation of state.
Details: Accurate temperature calculation is crucial for designing chemical processes, predicting phase behavior, and understanding gas properties under various conditions.
Tips: Enter the reduced temperature, Wohl parameter a, 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 (T/Tc).
Q2: How do I find Wohl parameter a?
A: Wohl parameter a is typically determined experimentally or from thermodynamic tables for specific substances.
Q3: What are typical units for critical molar volume?
A: Critical molar volume is usually expressed in m³/mol or L/mol (1 m³ = 1000 L).
Q4: Can this calculator be used for ideal gases?
A: No, this is specifically for real gases where intermolecular forces are significant.
Q5: What's the range of validity for this calculation?
A: The Wohl equation is most accurate near the critical point and becomes less accurate at very high pressures or temperatures.
