A thin

-

walled tube has its inner surface coated with polypropylene lining. The ASME Code for Process Piping limits the maximum use temperature for polypropylene lining to

107

.

The tube has a diameter of

4

.

Assume the tube behaves as a blackbody

and irradiation on the tube from the surroundings is negligible. Determine the maximum amount of total radiation emission rate per unit length of the tube that can be achieved without exceeding the maximum use temperature for polypropylene lining.

The

total radiation emission rate per unit length of the tube is W
