The humidity at dry-bulb temperature of 20^oC is 30% and the humidity

1.	The humidity at dry-bulb temperature of 20^oC is 30% and the humidity at dry-bulb temperature of 22^oC is 24%, what is the slope of adiabatic cooling line?(a) -0.01(b) -0.02(c) -0.03(d) -0.05The question was posed to me in my homework.My doubt is from Degrees of Freedom Analysis in Steady-State Process topic in division Humidity Charts & their Use, Analysis of the Degrees of Freedom in a Steady – State Process, Solving Material and Energy Balances Using Process and Unsteady State Material and Energy Balances of Basic Chemical Engineering
Answer» The correct CHOICE is (c) -0.03 To EXPLAIN: SLOPE of ADIABATIC cooling line = (0.3 – 0.24)/(20 – 22) = -0.03.
