Relative Humidity given partial pressure of water vapor Solution

STEP 0: Pre-Calculation Summary
Formula Used
Relative Humidity = Pressure of water vapour/Partial pressure of water vapour in saturated air
Φ = pv/ps
This formula uses 3 Variables
Variables Used
Relative Humidity - Relative Humidity is the ratio of the partial pressure of water vapor in the mixture to the vapor pressure of water at a given temperature.
Pressure of water vapour - (Measured in Pascal) - Pressure of water vapour is the pressure exerted by the water vapour in the moist air or the mixture of dry air and water vapour.
Partial pressure of water vapour in saturated air - (Measured in Pascal) - Partial pressure of water vapour in saturated air is obtained from the steam tables corresponding to dry bulb temperature.
STEP 1: Convert Input(s) to Base Unit
Pressure of water vapour: 60 Bar --> 6000000 Pascal (Check conversion here)
Partial pressure of water vapour in saturated air: 80 Bar --> 8000000 Pascal (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Φ = pv/ps --> 6000000/8000000
Evaluating ... ...
Φ = 0.75
STEP 3: Convert Result to Output's Unit
0.75 --> No Conversion Required
FINAL ANSWER
0.75 <-- Relative Humidity
(Calculation completed in 00.016 seconds)

What is Relative Humidity?

Relative humidity (RH) refers to the moisture content of the atmosphere, expressed as a percentage of the amount of moisture that can be retained by the atmosphere (moisture-holding capacity) at a given temperature and pressure without condensation.

How to Calculate Relative Humidity given partial pressure of water vapor?

Relative Humidity given partial pressure of water vapor calculator uses Relative Humidity = Pressure of water vapour/Partial pressure of water vapour in saturated air to calculate the Relative Humidity, The Relative Humidity given partial pressure of water vapor formula is defined as the ratio of actual partial pressure of water vapor in moist air at a given temperature to the partial pressure of water vapor in saturated air at the same temperature. Relative Humidity is denoted by Φ symbol.

FAQ

What is Relative Humidity given partial pressure of water vapor?
The Relative Humidity given partial pressure of water vapor formula is defined as the ratio of actual partial pressure of water vapor in moist air at a given temperature to the partial pressure of water vapor in saturated air at the same temperature and is represented as Φ = pv/ps or Relative Humidity = Pressure of water vapour/Partial pressure of water vapour in saturated air. Pressure of water vapour is the pressure exerted by the water vapour in the moist air or the mixture of dry air and water vapour & Partial pressure of water vapour in saturated air is obtained from the steam tables corresponding to dry bulb temperature.
How to calculate Relative Humidity given partial pressure of water vapor?
The Relative Humidity given partial pressure of water vapor formula is defined as the ratio of actual partial pressure of water vapor in moist air at a given temperature to the partial pressure of water vapor in saturated air at the same temperature is calculated using Relative Humidity = Pressure of water vapour/Partial pressure of water vapour in saturated air. To calculate Relative Humidity given partial pressure of water vapor, you need Pressure of water vapour (pv) & Partial pressure of water vapour in saturated air (ps). With our tool, you need to enter the respective value for Pressure of water vapour & Partial pressure of water vapour in saturated air and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
How many ways are there to calculate Relative Humidity?
In this formula, Relative Humidity uses Pressure of water vapour & Partial pressure of water vapour in saturated air. We can use 2 other way(s) to calculate the same, which is/are as follows -
  • Relative Humidity = Degree of saturation/(1-((1-Degree of saturation)*(Partial pressure of water vapour in saturated air/Total pressure of moist air)))
  • Relative Humidity = Mass of water vapor in moist air/Mass of water vapor in saturated air
