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: It helps in comparing the thermodynamic properties of different gases at similar conditions relative to their critical points.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ T_r = \frac{P_{gas}}{\frac{a}{6 \times \left(\frac{P_{gas}}{P_r}\right) \times \left(\left(\frac{V'_m}{V'_r}\right)^2\right)}} \]

Where:

\( T_r \) — Reduced Temperature (dimensionless)
\( P_{gas} \) — Pressure of Gas (Pascal)
\( a \) — Wohl parameter a (empirical parameter)
\( P_r \) — Reduced Pressure (dimensionless)
\( V'_m \) — Molar Volume of Real Gas (m³)
\( V'_r \) — Reduced Molar Volume (m³)

Explanation: The formula calculates reduced temperature based on Wohl's equation of state, incorporating both actual and reduced parameters.

3. Importance of Reduced Temperature Calculation

Details: Reduced properties are crucial for applying the principle of corresponding states, which allows prediction of a fluid's behavior based on its critical properties.

4. Using the Calculator

Tips: Enter all required parameters in appropriate units. All values must be positive numbers. The calculator will compute the reduced temperature.

5. Frequently Asked Questions (FAQ)

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

Q2: Why use reduced properties?
