Questions & Step-by-Step Solutions
If the relative humidity of the air is 60% at 25°C, what is the dew point temperature? (2020)
Steps
Concepts
Step 1: Identify the given values. The temperature (T) is 25°C and the relative humidity (RH) is 60%.
Step 2: Use the dew point approximation formula: Dew Point ≈ T - ((100 - RH) / 5).
Step 3: Substitute the values into the formula: Dew Point ≈ 25 - ((100 - 60) / 5).
Step 4: Calculate (100 - RH): 100 - 60 = 40.
Step 5: Divide the result by 5: 40 / 5 = 8.
Step 6: Subtract this value from the temperature: 25 - 8 = 17.
Step 7: The dew point temperature is approximately 17°C.
Dew Point Calculation
– Understanding how to calculate the dew point temperature using relative humidity and temperature.
Relative Humidity
– Knowledge of what relative humidity represents and its relationship to temperature and dew point.
