1. What is Temperature of Real Gas Calculator?

Definition: This calculator determines the actual temperature of a real gas using the Wohl equation parameters, reduced temperature, and critical pressure.

Purpose: It helps in thermodynamic calculations for real gases where ideal gas laws don't apply accurately.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( T_{rg} \) — Temperature of real gas (Kelvin)
• \( T_{r} \) — Reduced temperature (dimensionless)
• \( b \) — Wohl parameter b (empirical constant)
• \( P_{c} \) — Critical pressure (Pascal)
• \( [R] \) — Universal gas constant (8.314 J/mol·K)

Explanation: The formula relates the reduced temperature and critical parameters to the actual temperature of a real gas.

3. Importance of Temperature Calculation

Details: Accurate temperature determination is crucial for gas behavior prediction, process design, and safety calculations in chemical engineering.

4. Using the Calculator

Tips: Enter the reduced temperature, Wohl parameter b, and critical pressure. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is reduced temperature?
A: Reduced temperature is the ratio of the actual temperature to the critical temperature of the substance (T/T_c).

Q2: How do I find Wohl parameter b?
A: Wohl parameters are typically determined experimentally or from thermodynamic tables for specific substances.

Q3: What units should I use for critical pressure?
A: The calculator uses Pascals (Pa) for critical pressure. 1 atm = 101325 Pa.

Q4: Why is the universal gas constant important?
A: It provides the necessary conversion between pressure-volume units and temperature in thermodynamic equations.

Q5: Can this be used for any real gas?
A: This specific form applies when using the Wohl equation of state with parameter b.
