Definition: Saturated Pressure in Raoult's Law is the pressure at which a given liquid and its vapour or a given solid and its vapour can co-exist in equilibrium, at a given temperature.
Purpose: This calculator helps determine the saturated pressure of a component using the K-value expression in Raoult's Law.
The calculator uses the formula:
Where:
Explanation: The K value is multiplied by the total gas pressure to obtain the saturated pressure of the component.
Details: Accurate calculation of saturated pressure is crucial for vapor-liquid equilibrium calculations, distillation processes, and chemical engineering applications.
Tips: Enter the K value and total gas pressure in Pascals. Both values must be > 0.
Q1: What is the K value in Raoult's Law?
A: The K value is defined as the ratio of vapor-phase mole fraction to the liquid phase mole fraction.
Q2: What units should be used for pressure?
A: The calculator uses Pascals (Pa) for pressure units, but you can convert from other units before entering values.
Q3: How does temperature affect this calculation?
A: Temperature affects the K value, which should be determined at the system temperature before using this calculator.
Q4: Can this be used for multi-component systems?
A: This calculator is for single components. For mixtures, each component's saturated pressure must be calculated separately.
Q5: What's the range of typical K values?
A: K values typically range from 0 to 1 for most components, but can exceed 1 for light components at high temperatures.
