Solve the following points:

Transcribed Image Text:/For Air assume: v = 1.46 x 10-5 m²/s, p=1.225 kg/m³, y = 1.4 and R = 287J/Kg K a) In a steady incompressible two-dimensional flow the velocity vector in m/s is given as: V = (6x-6y)i + (5x-6y) J. With the aid of sketches give a clear account of the distortion of a rectangular fluid element (Figure Q1-1). Figure Q1-1 With clear explanation, determine whether this flow is irrotational. b) Give a brief definition of the boundary layer shape factor including a clear explanation of how the magnitude of the boundary layer shape factor is related to the boundary layer profile. Air is moving along one side of a flat plate at a constant speed of 40 m/s. The flat plate is 3 m long and its width is 1m. Measurement shows the momentum thicknesses of the laminar boundary layer at x₁ = 1.0 m and x₂ = 4.0 m are about 0.401 and 0.802 mm respectively. Estimate the frictional drag acting on the plate between x₁ and x2. c) Two flat plates (A and B) are orientated to a uniform flow as indicated in Figure Q1-2. If the boundary layer flow on these plates is laminar, determine the ratio of the total friction drag for plate A to that for plate B (i.e. Drag Ratio Draga). Draga Explain your answer. The wall shear stress acting on the plates has been given as Tw=Kx-0.5 where k is a known constant. Ignore any three dimensionality effects in the flow. B ? 10.0 m 10.0 m Figure Q1-2 2.0 m
