The humidity at dry-bulb temperature of 20oC is 12% and the humidity at dry-bulb temperature of 23oC is 3%, what is the slope of adiabatic cooling line?

The humidity at dry-bulb temperature of 20oC is 12% and the humidity at dry-bulb temperature of 23oC is 3%, what is the slope of adiabatic cooling line? Correct Answer -0.03

Slope of adiabatic cooling line = (0.12 – 0.03)/(20 – 23) = -0.03.
