Problem 2: A minivan is traveling at constant velocity with speed Uoo, where pressure is P and temperature is Too. The roof of the minivan can be approximated as a horizontal flat pate of length L. (a) Use the integral method with a second-order polynomial to estimate the thickness of the laminar boundary layer as a function of x along the roof. Also, estimate the shear stress on the roof as a function of x. (b) Compare solution above with the exact solution (i.e., the Blasius solution). Poo Too U y X
