Product description
25 Using experimental data obtained with the Ubbelohde viscometer, construct rheological curves in the coordinates P⋅τ = f (P), for solutions of ethyl cellulose of different molecular weight in toluene. Compare the magnitude of the shear stress Pm.
P⋅10-2, Pa 10.0 20.0 30.0 70.0 80.0 90.0
M1 = 3⋅104 τ1, s 735 350 232 98 86 76
M2 = 5⋅104 τ2, c 755 360 236 99 87 77
M3 = 7⋅104 τ3, c 795,375 246 102 90 79
