Steel rods (1% carbon) that are 1.5 m long and 2 cm in diameter are heated in a furnace to 850°C and then quenched in a water bath at 50°C for 40 s as part of a hardening process. Given the convective heat transfer coefficient is 750 W/m2K, find the average temperature of the rods when they are taken out of the bath. Show that lumping the rods is appropriate.

Question
Steel rods (1% carbon) that are 1.5 m long and 2 cm in diameter are heated in a furnace to
850°C and then quenched in a water bath at 50°C for 40 s as part of a hardening process. Given the convective heat
transfer coefficient is 750 W/m2K, find the average temperature of the rods when they are taken out of the bath.
Show that lumping the rods is appropriate.
