For which one of the following situations would Kendall’s tau be appropriate? a) The Mohs scale rates the hardness of minerals. If one mineral can scratch another, it is judged….
Calculate the initial humidity and percentage humidity.
1. Humidity and Wet Bulb Temperature. The humidity of an air– water vapor mixture is H = 0.030 kg H2O/kg dry air. The dry bulb temperature of the mixture is 60°C. What is the wet bulb temperature?
2. Dehumidification of Air. Air having a dry bulb temperature of 37.8°C and a wet bulb temperature of 26.7°C is to be dried by first cooling to 15.6°C to condense water vapor and then heating to 23.9°C.
a. Calculate the initial humidity and percentage humidity.
b. Calculate the final humidity and percentage humidity. [Hint: Locate the initial point on the humidity chart. Then, go horizontally (cooling) to the 100% saturation line. Follow this line to 15.6°C. Then, go horizontally to the right to 23.9°C.]
