Question: A long, V-shaped part is heat treated by suspending it in a tubular furnace with a diameter of 2 m and a wall temperature of

A long, V-shaped part is heat treated by suspending it in a tubular furnace with a diameter of 2 m and a wall temperature of 1000 K. The "vee" is I-m long on a side and has an angle of 60?. If the wall of the furnace and the surfaces of the part may be approximated as blackbodies and the part is at an initial temperature of 300 K, what is the net rate of radiation heat transfer per unit length to the part?

Furnace, T. = 1000 K. D= 2 m e- 60 -Part, T,

Furnace, T. = 1000 K. D= 2 m e- 60 -Part, T, - 300 K L-1m
