Consider two cases involving parallel flow of dry air at v = 1.0 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 × 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?
