A 3-m-high, 6-m-wide rectangular advertisement panel is attached to a 6-m-wide, 0.15-m-high rectangular concrete block (density = 2500kg/m') by two 5-cm-diameter, 6-m-high (exposed part) poles as shown in the figure. If the sign is to withstand 180 km/h winds from any direction, determine (a) the maximum drag force on the panel, (b) the drag force acting on the poles, and • (C) the minimum length L of the concrete block for the panel to resist the winds. Note: Take the density of air to be 1.25kg/m.

You are working for a glider manufacturer and have been asked to analyse the laminar boundary layer at a certain point on the smooth wing. The velocity profile at this point, ?(?), is given by:? =3A?C" −2A?C# +?A?C+? ?! δ δ δwhere δ is the boundary-layer thickness and ?$ is the velocity at the edge of the boundary layer. ? and ? are constants.Determine the values of ? and ? such that the primary boundary condi9ons for the velocity profile are sa9sfied. Is it necessary to apply any auxiliary boundary condi9ons?Evaluate the boundary-layer shape factor, H.At the point of separa9on, the wall shear stress goes from posi9ve to nega9ve. Thus, show that the boundary layer at this loca9on is on the point of separa9ng.Show that the pressure on the wing surface is increasing with downstream distance. Is this consistent with your calcula9ons showing that the boundary layer is approaching separa9on? Explain your reasoning.

Assume the surfaces are smooth and flat Consider both laminar and turbulent boundary layers. (Figure 1) Part A :Determine the drag acting on each side of the trailer truck.
An aeroplane has a rectangular planform wing with a span of 12 m and a chord of 2 m. The aircraft is flying at cruising speed of 62 m/s at an altitude of 3,200 m. Assume that the skin-friction drag on the wing can be approximated by the drag on a flat plate of the same dimensions at 0° incidence. Calculate the skin-friction drag and the maximum boundary layer thickness assuming (i) a completely laminar flow, and (ii) a completely turbulent flow. Assume μ = 1.63.10-5 N s/m², p = 0.89 kg/m³. Then, calculate the skin-friction drag accounting for transition at Recr= 5.105. What would the drag benefit be if transition was delayed to a Reynolds number of 106? What reduction in a propeller engine power would this imply in the cruise condition, assuming a propeller efficiency of 0.88?
