Sagot :
Option D will be the answer.
Given in the question,
Steps to calculate the Dew point temperature,
- Subtract 20°C from the original temperature.
- Add 1° for every 5points in the relative humidity R.
If the original temperature is 35°C,
Step 1,
Subtract 20°C → (35°- 20°) = 15°
Step 2,
Add 1° foe every 5 points,
Hence, Dew point temperature = [tex]15^\circ+\frac{1}{5}R[/tex]
If the dew point is 30°C, expression will be,
[tex]30^\circ=15^\circ+\frac{1}{5}R[/tex]
Therefore, Option D will be the answer.
