23. Solving a chemistry problem

2. Construct a differential radius distribution curve for a suspension of Prosyanovsky kaolin in aniline using the following experimental data of sedimentation analysis (t is the settling time for the point at which the tangent to the sedimentation curve is drawn):
t, s 60 300 600 1200 1500 1800
Q, % 15 54 76 88 92 100

Dispersed phase density p= 2.3*103 kg/m3, medium density p0 = 1.02*103 kg/m3, medium viscosity n= 4.43 *10–3 H*s/m2, height H = 1*10 -1m.
