What is the difference between the wet bulb and the dry bulb, and what is the dewpoint temperature?
The difference between wet bulb and dry bulb temperatures:
Example 1:
If the dry bulb temperature is 20°C and the wet bulb temperature is 17°C, the wet-bulb depression is 3°C. The wet-bulb depression defines the relative humidity,
Example 2:
If the dry bulb temperature is 16°C and the wet bulb temperature is 5°C, we can deduce that the dewpoint temperature will be significantly lower than the wet bulb temperature.
Explanation:
The wet-bulb depression is the difference between the wet bulb and dry bulb temperatures. It is used to calculate relative humidity. In the first example, the wet bulb is 17°C and the dry bulb is 20°C, so the wet-bulb depression is 3°C. The dewpoint temperature is the point at which the air reaches 100% relative humidity, meaning dew forms. In the second example, with a dry bulb temperature of 16°C and a wet bulb temperature of 5°C, we can infer that the dewpoint temperature will be significantly lower than the wet bulb temperature.
Final answer: What is the difference between the wet bulb and the dry bulb if the dry bulb is 20°C and the wet bulb is 17°C? What is the dewpoint temperature if the dry bulb is 16°C and the wet bulb is 5°C? The difference between wet bulb and dry bulb temperatures, known as wet-bulb depression, defines the relative humidity and calculates the dewpoint temperature. Example one's wet-bulb depression is 3°C. From the data in example two, we can deduce that the dewpoint temperature is significantly lower than the wet bulb temperature.
