QUESTION: 25

A 10 cm dia steam pipe, carrying steam at 180oC, is covered with an insulation (conductivity = 0.6 W/m.oC). It losses heat to the surroundings at 30oC. Assume a heat transfer co-efficient of 0.8 W/m2.oC for heat transfer from surface to the surroundings. Neglect wall resistance of the pipe and film resistance of steam. If the insulation thickness is 2 cms, the rate of heat loss from this insulated pipe will be
