Consider two cases involving parallel flow of dry air at V = 1 m/s, T _∞ = 45°C, and atmospheric pressure over an isothermal plate at T _s = 20°C. In the first case, Re _x.c = 5 x 10 ⁵ , while in the second case the flow is tripped to a turbulent state at x = 0 m. At what x- location are the thermal boundary layer thicknesses of the two cases equal? What are the local heat fluxes at this location for the two cases?
