Relative Saturation Solution

STEP 0: Pre-Calculation Summary

Formula Used

Relative saturation = 100*(Partial Pressure/Vapor Pressure of Pure Component A)
H_r = 100*(p_partial/PA^o)
This formula uses 3 Variables

Variables Used

Relative saturation - Relative saturation is the ratio of partial pressure of vapor to partial pressure of vapor at saturation.
Partial Pressure - (Measured in Pascal) - Partial Pressure is the notional pressure of that constituent gas if it alone occupied the entire volume of the original mixture at the same temperature.
Vapor Pressure of Pure Component A - (Measured in Pascal) - Vapor Pressure of Pure Component A is the pressure exerted by a liquid or solid molecules of only A in a closed system in which they are in equilibrium with the vapour phase.

STEP 1: Convert Input(s) to Base Unit

Partial Pressure: 7.5 Pascal --> 7.5 Pascal No Conversion Required
Vapor Pressure of Pure Component A: 2700 Pascal --> 2700 Pascal No Conversion Required

STEP 2: Evaluate Formula

< 8 Saturation Vapour Pressure Calculators

Reduced Saturation Vapor Pressure using Actual and Critical Saturation Vapor Pressure

Go Reduced saturation vapor pressure = Saturation Vapor Pressure/Critical saturation vapor pressure

Critical Saturation Vapor Pressure using Actual and Reduced Saturation Vapor Pressure

Go Critical saturation vapor pressure = Saturation Vapor Pressure/Reduced saturation vapor pressure

Saturation Vapor Pressure using Reduced and Critical Saturation Vapor Pressure

Go Saturation Vapor Pressure = Reduced saturation vapor pressure*Critical saturation vapor pressure

Saturation Vapor Pressure using Acentric Factor

Go Saturation Vapor Pressure = Critical saturation vapor pressure*( 10^(-(Acentric Factor+1)))

Critical Saturation Vapor Pressure using Acentric Factor

Go Critical saturation vapor pressure = Saturation Vapor Pressure/(10^(-(Acentric Factor+1)))

Relative Saturation

Go Relative saturation = 100*(Partial Pressure/Vapor Pressure of Pure Component A)

Percentage of saturation

Go Percentage of saturation = 100*(Molar humidity/Saturated molar humidity)

Reduced Saturation Vapor Pressure using Acentric Factor

Go Reduced saturation vapor pressure = 10^(-(Acentric Factor+1))

Relative Saturation Formula

Relative saturation = 100*(Partial Pressure/Vapor Pressure of Pure Component A)
H_r = 100*(p_partial/PA^o)

How do we calculate relative saturation?

Once you have the saturation vapor pressure and the actual vapor pressure, relative humidity can be computed by dividing the actual vapor pressure by the saturation vapor pressure and then multiplying by 100 to convert the quantity to a percent.

How to Calculate Relative Saturation?

Relative Saturation calculator uses Relative saturation = 100*(Partial Pressure/Vapor Pressure of Pure Component A) to calculate the Relative saturation, The Relative Saturation is the ratio of the partial pressure of vapor to the partial pressure of vapor at saturation (vapor pressure). Relative saturation is denoted by H_r symbol.

FAQ

What is Relative Saturation?

The Relative Saturation is the ratio of the partial pressure of vapor to the partial pressure of vapor at saturation (vapor pressure) and is represented as H_r = 100*(p_partial/PA^o) or Relative saturation = 100*(Partial Pressure/Vapor Pressure of Pure Component A). Partial Pressure is the notional pressure of that constituent gas if it alone occupied the entire volume of the original mixture at the same temperature & Vapor Pressure of Pure Component A is the pressure exerted by a liquid or solid molecules of only A in a closed system in which they are in equilibrium with the vapour phase.

How to calculate Relative Saturation?

The Relative Saturation is the ratio of the partial pressure of vapor to the partial pressure of vapor at saturation (vapor pressure) is calculated using Relative saturation = 100*(Partial Pressure/Vapor Pressure of Pure Component A). To calculate Relative Saturation, you need Partial Pressure (p_partial) & Vapor Pressure of Pure Component A (PA^o). With our tool, you need to enter the respective value for Partial Pressure & Vapor Pressure of Pure Component A and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
