In a particular air flow over a heated surface, the boundary layer temperature distribution is approximated as               u y T T T T s s 1 exp Pr where y is the distance normal to the surface and the Prandtl number is 0.7. If T[infinity] = 400 K, Ts = 300 K, and u[infinity]/ν = 5000 m-1 , what is the surface heat flux?
