A steel tube [k = 15 W/(mC)], with an outside diameter of 7.6 cm and a thickness
Fantastic news! We've Found the answer you've been seeking!
Question:
A steel tube [k = 15 W/(m°C)], with an outside diameter of 7.6 cm and a thickness of 1.3 cm is covered with an insulation material [k = 0.2 W/(m°C)] 2 cm thick. A hot gas at 330°C with a heat transfer coefficient of 400 W/m2.°C flows inside the tube. The outer surface insulation is exposed to cooler air at 30°C with a heat transfer coefficient of 60 W/(m2.°C). Calculate the heat loss from the tube to the air for a 10 m length of the tube.
