Consider two cases involving parallel flow of dry air
at V=V= 3.5 m/s, T∞=T∞=45°C, and atmospheric
pressure over an isothermal plate at Ts=Ts=20°C. In the first
case, Rex,c=Rex,c=5 × 105, while in the second
case the flow is tripped to a turbulent state at x=x=0 m. At
what xx‐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?
