Relative Humidity given Partial Pressure of Water Vapor Solution

STEP 0: Pre-Calculation Summary

Formula Used

Relative Humidity = Pressure of Water Vapor/Partial Pressure of Water Vapour in Saturated Air
Φ = p_v/p_s
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 Vapor - (Measured in Pascal) - Pressure of Water Vapor 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 Vapor: 60 Bar --> 6000000 Pascal (Check conversion here)
Partial Pressure of Water Vapour in Saturated Air: 91 Bar --> 9100000 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Φ = p_v/p_s --> 6000000/9100000

Evaluating ... ...

Φ = 0.659340659340659

STEP 3: Convert Result to Output's Unit

0.659340659340659 --> No Conversion Required

FINAL ANSWER

0.659340659340659 ≈ 0.659341 <-- Relative Humidity
