Question

Group I contains the types of fluids while Group II contains the shear stress - rate of shear relationship of different types of fluids, as shown in the figure. Group I Group II P. Newtonian fluid 1. Curve 1 Q. Pseudo plastic fluid 2. Curve 2 R. Plastic fluid 3. Curve 3 S. Dilatant fluid 4. Curve 4 5. Curve 5

Correct answer (C) P-2, Q-4, R-5, S-3 Solution Newtonian fluid (P) has a linear relationship between shear stress and rate of shear passing through the origin, which is Curve 2. Pseudo plastic fluid (Q) is shear-thinning, meaning its viscosity decreases with increasing shear rate, represented by Curve 4. Dilatant fluid (S) is shear-thickening, represented by Curve 3. Plastic fluid (R), specifically Bingham plastic, requires a certain yield stress before it starts to flow, represented by Curve 5. Thus, the correct match is P-2, Q-4, R-5, S-3. Turn this into a strength. Explore AI-powered practice and doubt support with Success Tracker.
