The equation that can be used to solve for RH is 25/9(DP-T) - 100
Given the formula for the dew point in degrees, Fahrenheit expressed as
To solve for the value of RH, we will make RH the subject of the formula;
Subtract T from both sides:
- DP - T = Â 9/25(100 - RH)
Multiply both sides by 25
25(DP - T) = 9(100 - RH)
25(DP - T) = 900 - 9RH
25(DP - T) - 900 = 9RH
RH = 25/9(DP-T) - 100
Hence the equation that can be used to solve for RH is 25/9(DP-T) - 100
