Definition: Reduced Pressure is the ratio of the actual pressure of the fluid to its critical pressure. It is dimensionless.
Purpose: This calculator determines the reduced pressure using the Wohl equation parameters.
The calculator uses the formula:
Where:
Details: Reduced properties are useful in thermodynamic calculations and help predict gas behavior under different conditions.
Tips: Enter the gas pressure, temperature, reduced temperature, and Wohl parameter b. All values must be > 0.
Q1: What is the Wohl equation?
A: The Wohl equation is a cubic equation of state used to model real gas behavior.
Q2: What are typical values for Wohl parameter b?
A: Values typically range from 0.001 to 0.1, depending on the gas.
Q3: What is reduced temperature?
A: It's the ratio of the actual temperature to the critical temperature of the substance.
Q4: Why use reduced properties?
A: They allow for generalized correlations that work for many substances.
Q5: What's the significance of the universal gas constant?
A: It's a fundamental physical constant that appears in many gas equations.
