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[in finity]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

The Surface heat flux is -9205 W/m^2

Explanation:

 Explanation is in the following attachment    

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
