Fig. 2 -- The time development of a square concentration profile injected at 305 kilofeet for particles of mass 1500.
The number above each concentration profile is the time in days for that profile. Input conditions for this
calculation were: M = 1500 atomic units, m= 28,97 atomic units, A = 4.63 x 1078 em, a= 1.70x 10-8 cm,
p = 1,72 x 107° gm/cm?®at 100 kilofeet, and T = 245°K.
