Saturation Pressure Calculator

Formula

To calculate the saturation pressure:

\[ P_{\text{sat}} = X_{\text{solv}} \times P_{\text{solv}} \]

Where:

\(P_{\text{sat}}\) is the Saturation Pressure (Pa)
\(X_{\text{solv}}\) is the mole fraction of the solvent
\(P_{\text{solv}}\) is the vapor pressure of the solvent (Pa)

What is Saturation Pressure?

Saturation pressure is the pressure at which a liquid's vapor is in equilibrium with its liquid phase at a given temperature. It is the maximum pressure that can be exerted by the vapor of the liquid at that temperature. This concept is crucial in various fields such as chemistry, physics, and engineering, particularly in understanding phase transitions and designing systems involving vapor-liquid equilibria.

Example Calculation 1

Let's assume the following values:

Mole Fraction of the Solvent (Xsolv) = 0.5
Vapor Pressure of the Solvent (Psolv) = 1000 Pa

Using the formula:

\[ P_{\text{sat}} = 0.5 \times 1000 = 500 \text{ Pa} \]

The Saturation Pressure is 500 Pa.

Example Calculation 2

Let's assume the following values:

Mole Fraction of the Solvent (Xsolv) = 0.8
Vapor Pressure of the Solvent (Psolv) = 1500 Pa

Using the formula:

\[ P_{\text{sat}} = 0.8 \times 1500 = 1200 \text{ Pa} \]

The Saturation Pressure is 1200 Pa.
