1. What is Reduced Temperature?

Definition: Reduced Temperature is the ratio of the actual temperature of the fluid to its critical temperature. It is dimensionless.

Purpose: It helps in comparing the thermodynamic properties of different substances at similar conditions.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ T_r = \frac{T_{rg}}{\frac{b \times 15 \times P_c}{[R]}} \]

Where:

Explanation: The formula calculates reduced temperature using Wohl parameter b and critical pressure.

3. Importance of Reduced Temperature

Details: Reduced temperature is crucial in thermodynamic calculations and helps predict gas behavior under various conditions.

4. Using the Calculator

Tips: Enter the temperature of real gas in Kelvin, Wohl parameter b, and critical pressure in Pascals. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is the significance of Wohl parameter b?
A: Wohl parameter b is an empirical parameter characteristic to equation obtained from Wohl model of real gas.

Q2: What is critical pressure?
A: Critical Pressure is the minimum pressure required to liquify a substance at the critical temperature.

Q3: What units should I use for input values?
A: Temperature should be in Kelvin, pressure in Pascals, and Wohl parameter b is unitless.

Q4: What does reduced temperature tell us?
A: It indicates how far the temperature is from the critical temperature, helping predict phase behavior.

Q5: What is a typical range for reduced temperature?
A: Values below 1 indicate subcritical conditions, while above 1 indicates supercritical conditions.
