Problem 3 (30 Points) Make a plot of v versus y at x 0.4 m from the leading edge of a flat plate for laminar flow with all the appropriate boundary laver approximations. The freestream velocity is 0.8 m/s. Take the kinematic viscosity to be 10.05x10 m'/s and the density to be 998.2 kg/m3. These are properties for water.
