5. Calculate the total number of particles n during the coagulation of carbon black particles during its coagulation under the action of ultrasound for the following time intervals: 1, 2,3,4,5,6,7,8,9,10 s. The average particle radius is r = 3*10 -8 m, the mass concentration of particles in 1m3 is 1.2*10-3 kg, the soot density is ρ = 1.9*103 kg/m3. Coagulation rate constant according to Smoluchowski's theory k=3*10-16 m3/s. Plot the curve of change in the total number of carbon black particles in the coordinates n=f(t).
