Abstract

Relative humidity is a sensitive parameter in the sciences. It impacts the physical performance of electrical devices, metals,agro-food and biological items to name just a few. There are numerous factors such as dew point temperature, ambient temperatureand solar radiation that can combine to influence relative humidity. There have been a handful of studies conductedon forecasting variations in relative humidity in the city of Biskra, Algeria. One typically finds that the dew point temperature isinvolved in variants of relative humidity, so we have been trying to predict it and create a semi-empirical equation as a functionof apparent solar time, influenced by maximum and minimum dew point temperature, rather than create a new correlationrelated with ambient temperature. This study aims to contribute relative humidity as a function of the dew point temperatureand validate it with experimental measurements.
