Here is how the Vapour Pressure of Air using Dalton's Law equation looks like.

3.0038 = 17.54 - (\frac{2907}{1.5})

3.0038mmHg = 17.54mmHg - (\frac{2907}{1.5})

3.0038 = 17.54 - (\frac{2907}{1.5})

Vapour Pressure of Air using Dalton's Law Solution

Follow our step by step solution on how to calculate Vapour Pressure of Air using Dalton's Law?

FIRST Step Consider the formula

e a = e s - (\frac{E}{K o})

Next Step Substitute values of Variables

∴

e a = 17.54mmHg - (\frac{2907}{1.5})

Next Step Convert Units

∴

e a = 2338.4679Pa - (\frac{2907}{1.5})

Next Step Prepare to Evaluate

∴

e a = 2338.4679 - (\frac{2907}{1.5})

Next Step Evaluate

∴

e a = 400.46788Pa

Next Step Convert to Output's Unit

∴

e a = 3.0037644199757mmHg

LAST Step Rounding Answer

∴

e a = 3.0038mmHg

Vapour Pressure of Air using Dalton's Law Formula Elements

Variables

Actual Vapour Pressure

Actual Vapour Pressure is the air in mm of mercury is the vapour pressure exerted by the water in the air.

Symbol: e_a

Measurement: PressureUnit: mmHg

Note: Value should be greater than 0.

Formulas to find Actual Vapour Pressure

Saturation Vapour Pressure

Saturation Vapour Pressure at Water Surface (mm of mercury) is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature.

Symbol: e_s

Measurement: PressureUnit: mmHg

Note: Value can be positive or negative.

Formulas to find Saturation Vapour Pressure

Evaporation from Water Body

Evaporation from water body (mm/day) is the process by which liquid water from an open water surface is converted directly to water vapor.

Symbol: E

Measurement: NAUnit: Unitless

Note: Value can be positive or negative.

Formulas to find Evaporation from Water Body

Proportionality Constant

The proportionality constant represented by 'Ko' is the ratio between two directly proportional quantities which depends upon the characteristics of the aquifer and the area of the well.
