Total Pressure Formula:
From: | To: |
Definition: This calculator determines the total pressure exerted by a mixture of water with an immiscible liquid based on their weights, molecular masses, and vapor pressure.
Purpose: It helps in chemical engineering and physical chemistry to understand the behavior of immiscible liquid mixtures.
The calculator uses the formula:
Where:
Explanation: The total pressure is the sum of the vapor pressure of pure component B and the additional pressure contribution from the water component.
Details: Understanding the total pressure of immiscible liquid mixtures is crucial for distillation processes, vapor-liquid equilibrium calculations, and chemical process design.
Tips: Enter the vapor pressure of pure component B, weights of both liquids, molecular masses (with water defaulting to 0.018 kg/mol). All values must be > 0.
Q1: Why is the molecular mass of water fixed at 0.018 kg/mol?
A: This is the standard molecular weight of water (18 g/mol converted to kg/mol).
Q2: What units should be used for input?
A: Use Pascals for pressure, kilograms for weights, and kg/mol for molecular masses.
Q3: Does this formula work for miscible liquids?
A: No, this formula is specifically for immiscible liquid mixtures.
Q4: How does temperature affect the calculation?
A: Temperature affects the vapor pressure value you input, but the formula itself is temperature-independent.
Q5: Can I use this for more than two immiscible liquids?
A: The formula would need to be extended to account for additional components.
