The humidity at dry-bulb temperature of 20^oC is 12% and the humidity

1.	The humidity at dry-bulb temperature of 20^oC is 12% and the humidity at dry-bulb temperature of 23^oC is 3%, what is the slope of adiabatic cooling line?(a) -0.01(b) -0.02(c) -0.03(d) -0.05This question was posed to me in an interview for job.This question is from Degrees of Freedom Analysis in Steady-State Process topic in section 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» RIGHT choice is (C) -0.03 Best EXPLANATION: Slope of adiabatic cooling LINE = (0.12 – 0.03)/(20 – 23) = -0.03.
