Definition: This calculator determines the ratio of weights of water to another immiscible liquid in a mixture based on their vapor pressures and molecular masses.
Purpose: It helps in distillation and separation processes where immiscible liquids are involved.
The calculator uses the formula:
Where:
Explanation: The ratio is calculated by multiplying water's partial pressure with its molecular mass, divided by the product of component B's vapor pressure and molecular mass.
Details: This ratio is crucial in steam distillation processes where immiscible liquids are separated based on their vapor pressures.
Tips: Enter the partial pressure of water, molecular mass of water (default 0.018 kg), vapor pressure of component B, and molecular mass of component B. All values must be > 0.
Q1: What is an immiscible mixture?
A: A mixture where two liquids don't dissolve in each other (like oil and water).
Q2: Why is molecular mass of water fixed at 0.018 kg?
A: This is the standard molecular mass of water (18 g/mol converted to kg).
Q3: Where do I find vapor pressure values?
A: Vapor pressure values can be found in chemical engineering handbooks or material safety data sheets.
Q4: What units should be used?
A: Use Pascals for pressure and kilograms for molecular mass for consistent results.
Q5: Can this be used for miscible liquids?
A: No, this formula is specifically for immiscible liquid mixtures.
