ACTIVITY 2Mixing RatioThe mixing ratio is the mass of water vapor in a unit of air compared to the remaining mass of dry air, commonlyexpressed as grams/kilogram (g/kg).Use Table 2, which presents the mixing ratios for saturated air at various temperatures, to complete the following.1. To illustrate the relationship between the amount of water vapor needed for saturation and temperature, prepare agraph by plotting the data from Table 2 on Figure 5.Table 2 Amount of Water Vapor Needed to Saturate 1 Kilogram of Airat Various Temperatures (the saturation mixing ratio)TEMPERATURESATURATION MIXING RATIO('C)(F)WATER-VAPOR CONTENT AT SATURATION (g/kg)-40-400.1-30-220.3-20-40.75-1014323.541105010155914206820257726.530863535954740104continued171 Atmospheric Moisture, Pressure, and WindActivity 2 continuedTemperature ('F)50°2.
