Temperature Formula:
From: | To: |
Definition: This calculator determines the actual temperature of a real gas using Wohl's equation of state, based on reduced temperature, critical pressure, and critical molar volume.
Purpose: It helps in thermodynamic calculations for real gases where ideal gas assumptions don't hold true.
The calculator uses the formula:
Where:
Explanation: The formula relates the actual temperature to reduced temperature and critical parameters through Wohl's equation.
Details: Accurate temperature determination is crucial for predicting gas behavior in industrial processes, chemical reactions, and thermodynamic systems.
Tips: Enter the reduced temperature (dimensionless), 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: Where can I find critical parameters?
A: Critical properties are tabulated in thermodynamic reference books for common substances.
Q3: Why use Wohl's equation?
A: Wohl's equation provides better accuracy for real gases than ideal gas law, especially near critical conditions.
Q4: What are typical critical pressure values?
A: Critical pressures vary widely - from 2.24 MPa for helium to 7.38 MPa for water.
Q5: How accurate is this calculation?
A: Accuracy depends on the quality of input parameters and how well Wohl's equation fits your specific gas.
