Abrass ingot weighing 200lbm and having a surface area of 3.5 sq ft is at a uniform temperature of 100 f. itâs placed in a furnace where itâs exposed to an atmosphere at 2200 f. the surface film coefficient between the ingot and the furnace atmosphere is estimated to be 50 btu/hr-sq ft f. assume that the ingot has a negligible internal thermal resistance. for brass â=550 lbm/cu ft and the specific heat c=0.100 btu/lbm-f. whatâs the time in minutes it will take for the ingot to reach a temperature of 1500f?
