3.38. Build a sedimentation curve, calculate and plot the integral and differential curves of the distribution of particles of Voronezh clay in water, using the graphical method of processing the sedimentation curve:
t, min 0.5 1 2 4 6 8 12 16 20 24
m, g 8 11 18 21 21 26 29 34 38 40 40
Settlement height H = 0,078 m; viscosity n = 1 * 10–3 Pa * s; clay density p = 2.72 * 103 kg / m3; the density of the dispersion medium p0 = 1 * 103 kg / m3.
