Partial Pressure of Water Vapour Solution

STEP 0: Pre-Calculation Summary

Formula Used

Partial Pressure = Pressure of Gas*1.8*Atmospheric Pressure*Temperature Difference/2700
p_partial = P_gas*1.8*P_atm*ΔT/2700
This formula uses 4 Variables

Variables Used

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.
Pressure of Gas - (Measured in Pascal) - The pressure of Gas is the force that the gas exerts on the walls of its container.
Atmospheric Pressure - (Measured in Pascal) - Atmospheric pressure, also known as barometric pressure, is the pressure within the atmosphere of Earth.
Temperature Difference - (Measured in Kelvin) - Temperature Difference is the measure of the hotness or the coldness of an object.

STEP 1: Convert Input(s) to Base Unit

Pressure of Gas: 0.215 Pascal --> 0.215 Pascal No Conversion Required
Atmospheric Pressure: 101325 Pascal --> 101325 Pascal No Conversion Required
Temperature Difference: 29 Kelvin --> 29 Kelvin No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

p_partial = P_gas*1.8*P_atm*ΔT/2700 --> 0.215*1.8*101325*29/2700

Evaluating ... ...

p_partial = 421.17425

STEP 3: Convert Result to Output's Unit

421.17425 Pascal --> No Conversion Required

FINAL ANSWER

421.17425 ≈ 421.1742 Pascal <-- Partial Pressure

What is Partial pressure?

The Partial pressure of a gas is a measure of thermodynamic activity of the gas's molecules. Gases dissolve, diffuse, and react according to their partial pressures, and not according to their concentrations in gas mixtures or liquids. This general property of gases is also true in chemical reactions of gases in biology.

How to Calculate Partial Pressure of Water Vapour?

Partial Pressure of Water Vapour calculator uses Partial Pressure = Pressure of Gas*1.8*Atmospheric Pressure*Temperature Difference/2700 to calculate the Partial Pressure, Partial pressure of Water Vapour which is the notional pressure of that constituent gas if it alone occupied the entire volume of the original mixture at the same temperature .The total pressure of an ideal gas mixture is the sum of the partial pressures of the gases in the mixture (Dalton's Law). Partial Pressure is denoted by p_partial symbol.

How to calculate Partial Pressure of Water Vapour using this online calculator? To use this online calculator for Partial Pressure of Water Vapour, enter Pressure of Gas (P_gas), Atmospheric Pressure (P_atm) & Temperature Difference (ΔT) and hit the calculate button. Here is how the Partial Pressure of Water Vapour calculation can be explained with given input values -> 421.1742 = 0.215*1.8*101325*29/2700.
