Present work shows that if a 'laminar' solution to Navier -Stokes equations can be found then skin friction and heat transfer coefficients for the turbulent case can readily be obtained. There is no need for Reynolds averaging and turbulence modelling. This can be done by defining a turbulence scaling factor which converts 'laminar' diffusivities to turbulent diffusivities. Using turbulent diffusivities in the laminar skin friction coefficient formula and laminar heat transfer coefficient formula gives the corresponding turbulent formula. Five different test cases with credible experimental measurements have been used to show the success of the present approach. This work also gives the lengths of internally generated turbulent eddies and roughness created turbulent eddies. If main flow mixes the turbulent eddies , smaller eddies are merged by the larger ones a...
