That is because in a turbulent flow (in a pipe or in a boundary layer) the transport of momentum and the transport of heat largely depends on the same turbulent eddies: the velocity and the temperature profiles have the same shape. The main assumption is that heat flux q/A in a turbulent system is analogous to momentum flux … on the wings of the angels
