Extracted text: 7.11 Consider two cases involving parallel flow of dry air at V = 2 m/s, T = 45°C, and atmospheric pressure over an isothermal plate at T, = 20°C. In the first case, Ree = 5 x 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 local heat fluxes at this loca- tion for the two cases?
