1. As part of your role at a heavy-goods vehicle manufacturer, you have been asked to determine the drag caused by the boundary layer developing along a section of the trailer roof, which can be treated as having constant pressure, as the truck travels at 10 m/s. The velocity profile in this region is given by: - A (+ 1) + 1 us where us is the velocity at the edge of the boundary layer. A and B are constants. d) The trailer roof has width 2 m. Use the von Karman integral momentum equation to determine the total drag contribution due to the boundary layer between x = 0.1 m and 0.5 m. Assume p = 1.3 kg/m³.

Problem6 When a viscous fluid flows parallel to a horizontal plate, it leads to the development of a thin boundary layer on the plate surface. The velocity within the boundary layer varies with the vertical direction as u(y) = US where 8(x) = 3.5 VX/Uis the boundary layer thickness vx 8(x) that increases with the horizontal position. Outside of the boundary layer, the flow is uniform and equal to the free stream velocity U... Show that for two fluids of different viscosities (₁, ₂) and densities (P₁, P2) and flowing at the same free stream velocity, the ratio of the drag force they generate on the plate is proportional to the square root of the ratio of the viscosities and densities: FD2 FD1 = H₂P2 M₁P₁
