11. (30, total, see breakdown below) A modern high-speed passenger train is 150 m long with a circumference of 10 m (approximately circular) and is traveling along the coast at 200 km/hr on a hot day (T = 30 deg C). Find the following: a. Fraction of train length on which there is a laminar BL. %3D 5 points 5 points 10 points 5 points 5 points b. BL thickness at the very end of the train. c. The skin friction drag of the train. d. The power required to overcome this drag. e. List any assumptions 11.
