1. Introduction to the Relative Humidity

Humidity is defined as the amount of water vapor in the air (i.e. (the gaseous water phase). The maximum water vapor that can hold by air is affected by temperature; the higher the temperature, the greater the amount of water vapor it can hold before reaching saturation. It indicates the presence of dew, frost, fog, and precipitation in the atmosphere. Humidity is often discussed in terms of absolute humidity and relative humidity.

$\bold{Absolute \space humidity}$
It measures the water content in the air, typically in units of grams per cubic meter. It is calculated by dividing the total mass of water vapor by the air volume. Given the same amount of water vapor in the air, the absolute humidity does not change with the temperature at a fixed volume. If the volume is not fixed, as in the atmosphere, absolute humidity changes in response to the volume changes caused by the temperature and pressure variation

$\bold{Relative \space humidity}$
It compares the current ratio of absolute humidity to the maximum humidity for a given temperature and expresses this value as a percentage. The higher the percentage, the higher the humidity. It is affected by both temperature and pressure. Given the same amount of water vapor, cooler air will have a higher relative humidity than warmer air. Relative humidity is a commonly used metric in weather reports and forecasts and is a good indicator of precipitation, dew, frost, fog, and apparent temperature. Apparent temperature is the temperature perceived by humans. In summer, the higher the relative humidity, the higher the apparent temperature. This results from a higher humidity, reducing the rate at which sweat evaporates, which increases the perceived temperature.

2. What is the Formulae used?

$\bold{Formula \space Used}$
$E_d = (6.112).(e^{\frac{(17.502.DB)}{(240.97+DB)}})$
$E_w = (6.112).(e^{\frac{(17.502.WB)}{(240.97+WB)}})$
R.H. = $\frac{(E_w - 0.6687451584)*(1+0.00115*WB)*(DB - WB)}{E_d}*100$
where
e = 2.71828182845904
DB = Dry Bulb Temperature (In Degree Celsius)
WB = Wet Bulb Temperature (In Degree Celsius)
N = 0.6687451584

3. What is the basic concept of Relative Humidity?

Relative Humidity is measured using a device called a Sling Psychrometer. This device consists of two sideways thermometers called Dry Bulb & Wet Bulb thermometers with a wetted wick at the bottom. When its attached handle swings around it, the air causes the water on the wick to evaporate, producing a lower temperature in the wet bulb thermometer. But here, we can calculate the Relative Humidity without this device by putting the Dry Bulb & Wet Bulb values in the formula. The equation of the formula is so complex that for ease, we have split it into 3 parts.
