In a particular application involving airflow over a surface, the boundary layer temperature distribution may be approximated as T−Ts/T[infinity]−Ts=1−exp⁡(−Pr(u[infinity]y)/????) Where y is the distance normal to the surface and the Prandtl number, Pr=cpμ/k=0.7, is a dimensionless fluid property. If T[infinity]=400K, Ts=300K, and u[infinity]/υ=5000 m-1, what is the surface heat flux? 6.11
