The humidity at dry-bulb temperature of 20oC is 30% and the humidity at dry-bulb temperature of 22oC is 24%, what is the slope of adiabatic cooling line?

The humidity at dry-bulb temperature of 20oC is 30% and the humidity at dry-bulb temperature of 22oC is 24%, what is the slope of adiabatic cooling line? Correct Answer -0.03

Slope of adiabatic cooling line = (0.3 – 0.24)/(20 – 22) = -0.03.
