(b) Under a temperature of 20C, an aviation fuel with a density of 844 kg/m and dynamic viscosity of 3.4x10 Pa.s, flows with a free stream velocity of 2 m/s over a plane 4 m long. If the velocity profile is that given in part a) above and the relationship of boundary layer thickness to distance from the leading edge is given by: (i) (ii) X II 5.48 Reg.5 At the trailing edge of the plane, determine the boundary layer thickness 8, displacement thickness *, and the momentum thickness 0. 1 At a height of 2 mm above the plane and at a position 2 m from the leading edge of the plane, calculate the velocity and shear stress.
