1. What is Reduced Temperature of Real Gas?

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

Purpose: This calculator determines the reduced temperature based on Wohl parameter b and actual/reduced pressure parameters.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ T_r = \frac{T_{rg}}{\left(\frac{b \times 15 \times \left(\frac{P_{rg}}{P_r}\right)}{[R]}\right)} \]

Where:

\( T_r \) — Reduced Temperature (dimensionless)
\( T_{rg} \) — Temperature of Real Gas (K)
\( b \) — Wohl Parameter b
\( P_{rg} \) — Pressure of Gas (Pa)
\( P_r \) — Reduced Pressure (dimensionless)
\( [R] \) — Universal gas constant (8.314 J/mol·K)

3. Importance of Reduced Temperature Calculation

Details: Reduced properties are essential in thermodynamics for creating generalized correlations between different substances.

4. Using the Calculator

Tips: Enter the temperature of real gas in Kelvin, Wohl parameter b, gas pressure in Pascals, and reduced pressure. 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: Why is reduced temperature dimensionless?
A: Because it's a ratio of two temperatures (actual temperature divided by critical temperature).

Q3: What's a typical range for reduced temperature?
A: For most gases, reduced temperature typically ranges from 0 to 2 in practical applications.

Q4: How accurate is this calculation?
A: Accuracy depends on the accuracy of input parameters and the applicability of the Wohl equation for your specific gas.

Q5: Can I use this for any gas?
A: The Wohl equation works best for non-polar or slightly polar gases at moderate pressures.
