6.4 Water at temperature of T =25 flows over one of the surfaces of a steel wall (AISI 1010) whose temperature is T=40. The wall is 0.35 m thick, and its other surface temperature is T=100. For steady state conditions what is the convection coefficient associated with the water flow ? What is the temperature gradient in the wall and in the water that is in contact with the wall? Sketch the temperature distribution in the wall and in the adjoining water.
