Reduced Volume Formula:
From: | To: |
Definition: Reduced Volume of a fluid is computed from the ideal gas law as the ratio of its actual volume to critical volume.
Purpose: It helps in comparing the thermodynamic properties of different gases at corresponding states.
The calculator uses the formula:
Where:
Explanation: The actual volume of gas is divided by its critical volume to obtain the reduced volume.
Details: Reduced properties are useful in the principle of corresponding states, which allows for generalized predictions of gas behavior.
Tips: Enter the actual volume of gas and its critical volume in liters. Both values must be > 0.
Q1: What does reduced volume tell us?
A: It indicates how the actual volume compares to the critical volume, helping predict gas behavior at different conditions.
Q2: What is critical volume?
A: The volume occupied by the unit mass of gas at critical temperature and pressure.
Q3: Can reduced volume be less than 1?
A: Yes, when the actual volume is less than the critical volume.
Q4: What are typical values for reduced volume?
A: Values vary widely depending on conditions, but often range between 0.5 and 10 for common applications.
Q5: How is this used in engineering?
A: Engineers use reduced properties to estimate gas behavior in pipelines, reactors, and other systems.
