22. Calculate and plot the change in the magnitude of the ultimate shear stress, depending on the concentration of the suspension of iron bitches in paraxylene. When using the method of tangential displacement of the plate, the following data were obtained:
Concentration of dispersed phase C,% 15.0 20.0 22.0 24.0 27.0
The greatest force F m ⋅10 2, H 0.28 1.26 2.10 2.38 2.94
The length of the plate is a = 0.7⋅10-2 m, width b = 0.5⋅10-2 m.
