Relative humidity/saturation vapor pressure of water

○ What is humidity? It is a numerical value that represents the amount of water vapor contained in the atmosphere as a ratio. Even at the same temperature, the perception differs with varying humidity levels. When humidity is high, it feels hotter. There are several indicators of humidity. This time, we will introduce the commonly used relative humidity. *For more details, please be sure to check the URL below.

basic information

○Relative Humidity Relative Humidity (%) = e/es × 100 In gases, the maximum amount of moisture that can be contained in the air (saturation vapor amount) changes with temperature. Therefore, relative humidity is calculated by comparing this maximum moisture amount with the amount of moisture present in the air. ○Saturation Vapor Pressure of Water ew (T) ln (ew/Pa) = -6096.9385/T + 21.2409642 - 2.711193×10^-2T + 1.673952×10^-5T² + 2.433502ln (T) *For more details, please refer to the URL above.
