A simple procedure for measuring surface convectionheat

Chapter 5, Problem 5.88

(choose chapter or problem)

A simple procedure for measuring surface convectionheat transfer coefficients involves coating the surfacewith a thin layer of material having a precise meltingpoint temperature. The surface is then heated and, bydetermining the time required for melting to occur, the convection coefficient is determined. The followingexperimental arrangement uses the procedure to deter-mine the convection coefficient for gas flow normal to asurface. Specifically, a long copper rod is encased ina super insulator of very low thermal conductivity, and avery thin coating is applied to its exposed surface.If the rod is initially at 25C and gas flow forwhich h?200 W/m2?K and T??300C is initiated,what is the melting point temperature of the coating ifmelting is observed to occur at t?400 s?
