Definitions from the Web

Wet-Bulb Thermometer

The wet-bulb thermometer is a device used for measuring the temperature by using the principle of evaporation. It consists of a normal thermometer with a wetted cloth or wick covering the bulb. As the moisture evaporates from the cloth, it lowers the temperature making the wet-bulb thermometer read lower than the dry-bulb thermometer.

Sense 1: Measuring Humidity

In meteorology, the wet-bulb thermometer is widely employed to measure humidity. By comparing the readings of the wet-bulb thermometer to the dry-bulb thermometer, the humidity or amount of moisture in the air can be determined.

Example sentence: The wet-bulb thermometer recorded a lower temperature than the dry-bulb thermometer, indicating high humidity in the air.

Sense 2: Evaluating Heat Stress

Wet-bulb thermometers are crucial tools for determining heat stress levels. They are commonly used in occupational health to assess conditions that impact workers' comfort and safety. By measuring both the dry-bulb and wet-bulb temperatures, the wet-bulb globe temperature (WBGT) index can be calculated and used to determine appropriate work-rest schedules in hot environments.

Example sentence: The WBGT index, obtained by means of a wet-bulb thermometer, revealed extreme heat stress conditions on the factory floor, leading to the adoption of necessary preventive measures.

Sense 3: Environmental Studies

Wet-bulb thermometers also find application in environmental studies and research. They assist scientists in understanding the ecological impact of temperature and humidity on various ecosystems and species. By collecting wet-bulb temperature data over time, researchers can analyze climate trends and patterns.

Example sentence: The wet-bulb thermometer readings helped determine the optimal conditions required for the growth of a specific species of plant in the rainforest.
