The humidity at dry-bulb temperature of 20oC is 10% and the humidity at dry-bulb temperature of 23oC is 4%, what is the slope of adiabatic cooling line?

The humidity at dry-bulb temperature of 20oC is 10% and the humidity at dry-bulb temperature of 23oC is 4%, what is the slope of adiabatic cooling line? Correct Answer -0.02

Slope of adiabatic cooling line = (0.1 – 0.04)/(20 – 23) = -0.02.
