3.34. Calculate and plot the integral and differential distribution curves for suspensions of alumina in methanol from the results of processing the sedimentation curve:
t, min 2 3 5 10 20 30 50 80 120 150
m, mg 19 31 46 57 65 69 74 78 80 80
The density of the dispersed phase p = 3.9 * 103 kg / m3; the density of the dispersion medium p0 = 0.79 · 103 kg / m3; viscosity n = 1.2 * 10–3 Pa * s; sedimentation height H = 0.08 m. Use the method of constructing tangents to the sedimentation curve.
