Reduced Molar Volume Formula:
From: | To: |
Definition: Reduced Molar Volume of a fluid is computed from the ideal gas law at the substance's critical pressure and temperature per mole.
Purpose: It helps in comparing the properties of real gases at different conditions using the principle of corresponding states.
The calculator uses the formula:
Where:
Explanation: The actual molar volume is divided by the critical molar volume to obtain the reduced property.
Details: Reduced properties are crucial in thermodynamics for creating generalized correlations that can be applied to many substances.
Tips: Enter the molar volume of real gas in m³ and critical molar volume in m³/mol. All values must be > 0.
Q1: What is the physical significance of reduced molar volume?
A: It represents how the actual volume compares to the critical volume, indicating the state of the substance relative to its critical point.
Q2: What's a typical range for reduced molar volume?
A: Values typically range from 0.1 to 10, with 1 representing the critical point.
Q3: How do I find the critical molar volume?
A: Critical molar volume is a substance-specific property that can be found in thermodynamic tables or databases.
Q4: Can this be used for all gases?
A: Yes, but accuracy may vary for polar or complex molecules.
Q5: What are common applications of reduced properties?
A: Used in equations of state, phase equilibrium calculations, and thermodynamic modeling.
