143. Solving a chemistry problem

3.29. Calculate and plot the integral and differential distribution curves for a suspension of Glukhov clay in water from the following experimental data:
t, min 1 2 3 5 10 15 20 25 30 35
m, mg 6.5 12 17.5 25 37 44 47.5 49 50 50
Settlement height N = 0.15 m; viscosity n = 1 * 10–3 Pa * s; clay density p = 2.74 * 103 kg / m3; the density of the dispersion medium is p0 = 1 * 10 ^ 3 kg / m3. Use the method of constructing tangents to the sedimentation curve:
