Extracted text: Use the psychrometric charts to answer the following problems: I. The wet bulb and dry bulb temperature of air at 1 atm in a mixture are 40°C and 60°C, respectively. Find its (a) absolute humidity, (b) molal humidity, (c) relative humidity, (d) humid volume, and (e) dew point temperature II. An air-water vapor sample at 14.7 psia and 140°F has an absolute humidity of 0.0100 lb water/lb dry wair. Find its (a) relative humidity, (b) percentage humidity, (c) wet-bulb temperature (d) dew point temperature and the (e) partial pressure of water vapor in the sample.
