Question
Use the Köhler curves shown in Fig. 6.3 to estimate: 30 25 20 co 15 10 6.11 (a) The radius of the droplet that will Condensation-freezing yaler form on a sodium chloride particle of mass 10-18 kg in air that is 0.1 % supersaturated Deposition (b) The relative humidity of the air adjacent to a droplet of radius 0.04 pm that contains 10-19 kg of dissolved ammonium sulfate. 0 10 15 Temperature (°C) 0 -5 20 -25 Fig. 6.30 Onset of ice nucleation as a function of tempera- ture and supersaturation for various compounds. Conditions for condensation-freezing and ice deposition are indicated. Ice nucleation starts above the indicated lines. The materials are silver iodide (red), lead iodide (blue), methaldehyde (violet) and kaolinite (green). [Adapted from J. Atmos. Sci. 36, 1797 (1979).] (c) The critical supersaturation required for an ammonium sulfate particle of mass 10-19 kg to grow beyond the haze state.Explanation / Answer
e'/es is used to calculate supersaturated and relative humidity of an air adjacent to the solution droplet of specified radius r.
an initially dry sodium chloride particle of mass 10^-19 were placed in air with RH equal to 90%, water vapour would condense on the particle the salt would dissolve and a solution droplet of r =0.05mm would form
B)This RH is not shown as graph the sensitvity near 1.00s RH =88%.
C) SS=0.0055%=0.55%
