85. Solving a chemistry problem

3.27. Calculate and plot integral and differential particle distribution curves for Al2O3
in water according to the following experimental data:
t, s 60 150 300 360 450 1000 2400
m, mg 4 7 29 31 42 50 50
Settling height H = 0.08 m; medium viscosity n= 1.2 *10–3 Pa* s; density Al2O3 p= 4*10^3 kg/m3
; water density p0 = 1*103 kg/m3. Use the method of constructing tangents to the sedimentation curve.
