Dew Point Depression Solution

STEP 0: Pre-Calculation Summary

Formula Used

Dewpoint Depression = Temperature-Dewpoint Temperature
dpd = T-dpt
This formula uses 3 Variables

Variables Used

Dewpoint Depression - (Measured in Kelvin) - Dewpoint Depression is the difference between the temperature and dew point temperature at a certain height in the atmosphere.
Temperature - (Measured in Kelvin) - Temperature is the degree or intensity of heat present in a substance or object.
Dewpoint Temperature - (Measured in Kelvin) - Dewpoint Temperature is defined as the temperature to which the air would have to cool (at constant pressure and constant water vapor content) in order to reach saturation.

STEP 1: Convert Input(s) to Base Unit

Temperature: 85 Kelvin --> 85 Kelvin No Conversion Required
Dewpoint Temperature: 100 Kelvin --> 100 Kelvin No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

dpd = T-dpt --> 85-100

Evaluating ... ...

dpd = -15

STEP 3: Convert Result to Output's Unit

-15 Kelvin --> No Conversion Required

FINAL ANSWER

-15 Kelvin <-- Dewpoint Depression

FAQ

What is Dew Point Depression?

Dew Point Depression (T-Td) is the difference between the temperature and dew point temperature at a certain height in the atmosphere and is represented as dpd = T-dpt or Dewpoint Depression = Temperature-Dewpoint Temperature. Temperature is the degree or intensity of heat present in a substance or object & Dewpoint Temperature is defined as the temperature to which the air would have to cool (at constant pressure and constant water vapor content) in order to reach saturation.

How to calculate Dew Point Depression?

Dew Point Depression (T-Td) is the difference between the temperature and dew point temperature at a certain height in the atmosphere is calculated using Dewpoint Depression = Temperature-Dewpoint Temperature. To calculate Dew Point Depression, you need Temperature (T) & Dewpoint Temperature (dpt). With our tool, you need to enter the respective value for Temperature & Dewpoint Temperature and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
