Question

Question 6: Consider the high Reynolds number flow of fluid of density p viscosity p and speed U, past a plate of dimensions Lx L with negligible thickness. Assume a

laminar boundary layerdevelops. /8 (a) Estimate with rationale the magnitude of the drag force in configuration Figure 2a). (b) Estimate with rationale the magnitude of the drag force in configuration Figure 2b). (c) Find the ratio of the magnitudes and discuss the relation with the Reynolds number ReL.
