Actual Humidity Solution

Follow our step by step solution on how to calculate Actual Humidity?

FIRST Step Consider the formula

H a = H s \cdot H r

Next Step Substitute values of Variables

∴

H a = 60kg/m³ \cdot 0.25

Next Step Prepare to Evaluate

∴

H a = 60 \cdot 0.25

LAST Step Evaluate

∴

H a = 15kg/m³

Actual Humidity Formula Elements

Variables

Actual Humidity

Actual Humidity is the ratio of the partial pressure of water vapor in the air to the saturation vapor pressure at a given temperature, expressed as a percentage.

Symbol: H_a

Measurement: Mass ConcentrationUnit: kg/m³

Note: Value should be greater than 0.

Formulas to find Actual Humidity

Saturated Humidity

Saturated Humidity refers to the state where the air contains the maximum amount of water vapor it can hold at a given temperature and pressure, often leading to condensation.

Symbol: H_s

Measurement: Mass ConcentrationUnit: kg/m³

Note: Value should be greater than 0.

Formulas to find Saturated Humidity

Relative Humidity

Relative Humidity is the ratio of the partial pressure of water vapor in the air to the saturation vapor pressure at a given temperature, expressed as a percentage.

Symbol: H_r

Measurement: NAUnit: Unitless

Note: Value should be between 0 to 1.

Formulas to find Relative Humidity

Other formulas in Humidity Measurement category

Go Saturated Humidity

H s = \frac{H a}{H r}

Go Humidity ratio

H = \frac{M wv}{M gas}

Go Mass of Water Vapor in Mixture

M wv = H \cdot M gas

Go Mass of Dry Air or Gas in Mixture

M gas = \frac{M wv}{H}

How to Evaluate Actual Humidity?

Actual Humidity evaluator uses Actual Humidity = Saturated Humidity*Relative Humidity to evaluate the Actual Humidity, The Actual Humidity formula is defined as the current amount of water vapor in the air based on the maximum amount the air can hold at a given temperature (saturated humidity) and the current relative humidity. Actual Humidity is denoted by H_a symbol.

How to evaluate Actual Humidity using this online evaluator? To use this online evaluator for Actual Humidity, enter Saturated Humidity (H_s) & Relative Humidity (H_r) and hit the calculate button.

FAQs on Actual Humidity

What is the formula to find Actual Humidity?

The formula of Actual Humidity is expressed as Actual Humidity = Saturated Humidity*Relative Humidity. Here is an example- 1.75 = 60*0.25.

How to calculate Actual Humidity?

With Saturated Humidity (H_s) & Relative Humidity (H_r) we can find Actual Humidity using the formula - Actual Humidity = Saturated Humidity*Relative Humidity.

Can the Actual Humidity be negative?

No, the Actual Humidity, measured in Mass Concentration cannot be negative.

Which unit is used to measure Actual Humidity?

Actual Humidity is usually measured using the Kilogram per Cubic Meter[kg/m³] for Mass Concentration. Kilogram per Liter[kg/m³], Gram per Liter[kg/m³], Milligram per Liter[kg/m³] are the few other units in which Actual Humidity can be measured.
