1. Air at 30°C (v=1.6x10-m-/s) flows at a uniform speed of 8 m/s along a smooth 10-m-long flat plate. Assume that turbulent boundary layer follows the one-seventh-power law. (a) Calculate the approximate x-location along the plate where the boundary layer begins the transition process toward turbulence and the boundary layer thickness 8 at this location. (Hint: For a smooth flat plate, the boundary layer begins the transition process toward turbulence at a local Reynolds number of about 103) (b) At approximately what x-location along the plate is the boundary layer likely to be fully turbulent? What is the value of the local skin friction coefficient at this location? (Hint: For a smooth flat plate, the boundary layer is likely to be fully turbulent at a local Reynolds number of about 3x10%)
