Exercise 2 Moist air at 1 atm. barometric pressure has a dry bulb temperature of 40°C and a wet bulb temperature of 32°C. Using the equations for the moist air properties calculate: a) the partial pressure of the water vapor b) humidity ratio c) relative humidity d) dew-point temperature e) density of dry air in the mixture f) enthalpy of moist air using the perfect gas law
