1. Consider two cases involving parallel flow of dry air at V = 1 m/s, T = atmospheric pressure over an isothermal plate at T, 10°, 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 45°C, and = 20°C. In the first case, Rex,c = 5 x local heat fluxes at this location for the two cases?
