Peng-Robinson equation
The Peng-Robinson equation is a mathematical model used by engineers to predict how gases and liquids behave under different conditions. It helps determine properties like pressure, temperature, and volume for substances, especially when they are close to changing states (like boiling or condensing). This equation accounts for the fact that molecules attract and repel each other, making it more accurate for real-world substances than simpler models. It’s widely used in the oil and gas industry for designing equipment and processes to ensure safe and efficient operation.
