For the case of a turbulent boundary layer on a flat plate, the velocity profile has been shown to follow closely the form

Assuming a temperature profile of the same form, that is

and assuming that
 use the integral relation for the boundary layer to solve for h_x
and Nu_x. The temperature gradient at the surface may be considered similar to the velocity gradient at y
 0 given by equation (13-26).
