5. A fan that can provide air speeds up to 30 m/s is to be used in a low-speed wind tunnel with atmospheric air at 23°C. If one wishes to use the wind tunnel to study flat-plate boundary layer behavior up to a Reynolds number of 107, 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 was Re.c-5 × 105?

Problem 4 Air at 100 C flows across a thin, flat plate of subliming naphthalene that is 3.4 m long. The Reynolds number at the trailing edge of the plate is at the upper limit for a laminar boundary layer (Re 5e5). Estimate: (a) the average rate of sublimation in kmol/s*m2; and (b) the local rate of sublimation 0.5 m from the leading edge. Vapor pressure of naphthalene = 10 torr viscosity of air 0.0215 cP; molar density of air...
