Problem 1: The roof of a minivan is approximated as a horizontal flat pate of length L = 3 m, where V = 20 and 40 miles per hour. Assume standard pressure and temperature. (a) Is the flow laminar or turbulent on the roof? (b) Estimate the thickness of the boundary layer at x = 1 m for the two minivan speeds? (c) What is the displacement thickness at x = 1 when V = 40 MPH? (d) What is momentum thickness at x = 1 when V = 40 MPH? (e) What is the shear stress on the minivan roof when V = 40 MPH?
