The formula to calculate the relative humidity is:
\[ RH = \left( \frac{Pw}{Ps} \right) \times 100 \]
Where:
Psychrometrics is the study of the physical and thermodynamic properties of gas-vapor mixtures. The term comes from the Greek words ‘psycho’ meaning cold and ‘metrics’ meaning measurement. It is primarily used in the field of engineering, particularly in HVAC (heating, ventilation, and air conditioning) to understand the behavior of air under varying conditions of temperature, pressure, and humidity. This helps in designing and optimizing air conditioning and heating systems.
Let's assume the following values:
Using the formula:
\[ RH = \left( \frac{1200}{2000} \right) \times 100 = 60 \% \]
The Relative Humidity is 60%.
Let's assume the following values:
Using the formula:
\[ RH = \left( \frac{800}{1600} \right) \times 100 = 50 \% \]
The Relative Humidity is 50%.
