EX2: Cylindrical Shell
Consider a 10 mm thick polyvinyl chloride (PVC) tube 50 mm
in inside diameter and 3 m long. There is a heater which fits into the
center of the tube generating heat uniformly at a rate of 200
watts/meter of length. The thermal conductivity of the tube is 0.15 W/
mK. Assume no heat escapes at the ends of the tube.
