# Wet Bulbs Calculator

To calculate the temperature of the wet bulb, enter the temperature and relative humidity into the calculator's input boxes, then press the calculate button. Our free Wet Bulb Calculator rapidly calculates the temperature of a wet bulb.

### What is Wet Bulb Temperature?

The lowest temperature in the air that can only be reached through evaporation is called a wet bulb. The wet-bulb temperature is the lowest temperature that evaporative cooling alone can achieve for a portion of air. Only when the air humidity is 100% does the wet-bulb temperature become the normal temperature. The wet-bulb temperature will be lower than the normal temperature as the humidity in the air decreases.

The formula for calculating the temperature of a wet-bulb is as follows:

**Tw = T * arctan[0.151977 * (rh% + 8.313659)^(1/2)] + arctan(T + rh%) - arctan(rh% - 1.676331) + 0.00391838 *(rh%)^(3/2) * arctan(0.023101 * rh%) - 4.686035**

- Where,
- Tw = temperature of a wet bulb.
- T = the temperature of the air, which may be determined with a thermometer.
- rh% = The relative humidity is expressed as a percentage. It's the proportion of water vapour in the air to water at a given temperature.

### Wet Bulb Globe Temperature

This is a type of apparent temperature. The effect of humidity, temperature, solar light, and wind speed on humans is estimated using wet-bulb globe temperature. The temperature equation for a wet bulb globe is as follows

**WBGT = 0.7 * Tw + 0.2 * Tg + 0.1 * T** Where, Tg = temperature of a globe thermometer.

**WBGT = 0.7 * Tw + 0.3 * T** is the another formula

### How to Calculate the Temperature of a Wet Bulb?

The steps to quickly determine the temperature of a wet-bulb are given below.

### Applications of Wet-Bulb Calculators

Although the wet-bulb temperature is a lesser-known metric, it serves a useful purpose

- Snowmaking: Snowmaking necessitates cold temperatures, and as humidity falls, the temperature rises.
- Construction: because different materials react differently to varying levels of humidity, this temperature is required when creating a structure for different climates.
- Forecasters: Forecasters utilise wet-bulb temperature to predict rain, snow, or freezing rain in meteorology.

### FAQs on Wet Bulbs Temperature

**1. How do you determine the temperature of a wet-bulb?**

To begin, use a thermometer to determine the ambient temperature. Substitute these numbers for the relative humidity in the wet-bulb formula's temperature. To get the temperature value, perform the math procedures.

**2. What can the wet-bulb calculator be used for?**

The wet-bulb temperature is used in construction to determine the humidity and temperature of various materials, as well as in snowmaking and meteorology.

**3. What is the difference between the temperature of a dry bulb and the temperature of a wet-bulb? **

The temperature of adiabatic saturation is the temperature of the wet bulb. The usual air temperature is the dry-bulb temperature. A thermometer with a bulb covered in wet muslin can be used to measure wet bulb temperature, whereas a thermometer freely exposed to the air can be used to measure dry bulb temperature.

**4. How do you determine the difference between a wet and a dry bulb's dew point?**

On the left side of the "Dew-point Temperatures" ESRT, find the dry-bulb temperature, then on the top of the chart, discover the difference between the wet and dry-bulb temperatures, commonly known as the wet-bulb depression. The dew-point is visible where these rows meet.
