Relative Humidity: Definition, Measurement and its Importance in Atmospheric Water Generation

To understand how Rain ofLife atmospheric water generators work, it is essential to understand the concept of relative humidity. Have you ever wondered exactly what it is and how it is measured? In this article, we will explore this concept and how it controls the condensation process that produces high quality water.

What is relative humidity and how is it measured?

Relative humidity (RH) is a measure that expresses the amount of water vapour present in the air relative to the maximum amount it can contain at a given temperature. It is expressed as a percentage, where 100% represents the absolute saturation of the air.

It is measured using a device called a hygrometer. Hygrometers use different technologies, such as capacitance, resistance or psychrometry, to measure relative humidity accurately. Some modern hygrometers are even equipped with probes that can be placed in different locations for more accurate measurements.

Importance of relative humidity in atmospheric water generation

Relative humidity plays a crucial role in Rain ofLife’s process of generating quality drinking water. To generate water from ambient humidity, it is necessary to cool the air until its temperature reaches the dew point and the water vapour begins to condense.

But what is the dew point? The dew point is the temperature at which the air is cooled sufficiently that its relative humidity reaches 100% and the water vapour condenses into a liquid.

The dew point and its relation to relative humidity and temperature

As temperature decreases, the ability of the air to hold water vapour decreases, which in turn increases the likelihood that the dew point will be reached. If the relative humidity is high, the dew point will be reached at a higher temperature compared to a low relative humidity. On the other hand, if the relative humidity is low, a lower temperature will be required to reach the dew point.

The influence of atmospheric humidity on water generation

Atmospheric humidity is a measure that describes the absolute amount of water vapour present in the air as a function of air volume.It is expressed in grams of water vapour per cubic metre of air (g/m³). This measure determines the amount of water that can be extracted from the air in a given volume.H2: In short, what is the relationship between relative humidity and atmospheric humidity? Relative humidity and atmospheric humidity are related, but they are not the same concept.Relative humidity expresses the amount of water vapour in the air in relation to the maximum water holding capacity of the air at a given temperature.On the other hand, atmospheric humidity indicates the absolute amount of water vapour present in the air without taking into account the temperature and the holding capacity of the air. Both measurements are relevant in atmospheric water generation, as they influence the amount of water that can be obtained from the ambient air.

Understanding these definitions allows us to better understand how the condensation process occurs to obtain high quality water, as is done by Rain of Life atmospheric water generators.
