Question
Consider two cases involving parallel flow of dry air at V = 4m/s, T, = 45°C, and atmospheric pressure over an isothermal plate at
T, = 20°C. In the first case, Re = 5 x 105, while in the second case the flow is tripped to a turbulent state at x = 0m. At what x
-location, in m, are the thermal boundary layer thicknesses of the two cases equal? What are the local heat fluxes, in W/m?, at this
location for the two cases?
