A laminar boundary layer velocity profile is given by: 11 U sin Ty 28 where u is fluid main stream velocity, & is physical thickness of the boundary layer and uis fluid velocity at vertical distance y from the solid boundary. Determine C, C, and C, in the following equations; 8 i) Re, = C 0 Re, = C iii) Re, = C, X where x is a distance of boundary layer from leading edge, &* is displacement thickness, is momentum thickness and Re, is Reynolds number at point x.
