Steel rods (ρ =7832 kg/m3, cp=434 J/kg·K and k=639 W/m·K) are heated in a furnace to 850 and then quenched in a water bath at 50 for a period of 40 seconds as part of a hardening process. The convection heat transfer coefficient is 650 W/m2·K.
If the steel rods have diameter of 40mm and length of 2m, determine their average temperature when they are taken out of the water bath. (풀이)...
