Asteel 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. if the outer surface of the insulation is exposed to cooler air at 30°c with a heat transfer coefficient of 60 w/m2.°c, determine: i) the heat loss from the tube to the air for a 10 m length of tube. il) the outer surface temperature of the insulation material.
