Question

Please help me get the correct answer quickly, please. :(( 

Consider two cases involving parallel flow of dry air at V = 3 m/s, T, = 45°C, and atmospheric pressure over an isothermal plate at T, = 20°C. In the first case, Ree = 5x 105, while in the second case the flow is tripped to a turbulent state at x = 0 m. At what xr-location, in m, are the thermal boundary layer thicknesses of the two cases equal? What are the local heat fluxes, in W/m2, at this location for the two cases? X = W/m? q'urb W/m?
