143. Solving a chemistry problem

3.31. Build the distribution curve of the suspension of zinc oxide ZnO in acetone using the following experimental data obtained by graphically processing the sedimentation curve (t is the sedimentation time for the point at which the tangent to the sedimentation curve is drawn):
t, s 60 180 300 600 900 1800 3600
Q,% 27 16 19 9 16 8 5
Density ZnO p = 5.66 * 103 kg / m3, density of the medium p0 = 0.79 * 103 kg / m3, viscosity of the medium n = 0.33 * 10–3
  H * s / m2. Height H = 10 * 10–2 m.
