Steel rods (ρ = 7832kg/m3, cp = 434j/kg.K, and k = 63.9W/m.K) are heated in a furnace to 850°C and then quenched in a water bath at 50°C for a period of 40 seconds as part of a hardening process. The convection heat transfer coefficient is 650W/m2.K. If the steel rods have a diameter of 40mm and length of 2m, determine their average temperature when they are taken out of the water bath.
