A fan that can provide air speeds up to 45 m/s is to be used in a low-speed wind tunnel with atmospheric air at 25ºC. If one wishes to use the wind tunnel to study flatplate boundary layer behavior up to Reynolds numbers of Rex = 108, what is the minimum plate length that should be used? At what distance from the leading edge would transition occur if the critical Reynolds number were Rex, c= 5 x105?
