Answer:
The temperature of the strip as it exits the furnace is 819.15 °C
Explanation:
The characteristic length of the strip is given by;

The Biot number is given as;

< 0.1, thus apply lumped system approximation to determine the constant time for the process;

The time for the heating process is given as;

Apply the lumped system approximation relation to determine the temperature of the strip as it exits the furnace;

Therefore, the temperature of the strip as it exits the furnace is 819.15 °C
