Question:
300oC steam flows in a stainless-steel (ss.) pipe with thermal conductivity of 50 W/m.K. The pipe has internal diameter (ID) of 40 cm, and outer diameter (OD) of 42 cm. The pipe is placed in another ss. pipe with ID and OD 44 cm and 44.2 cm, respectively. The gap between the pipes is filled with steel air (use air properties at 160oC from appendix). The convection heat transfer coefficient at the inner and the outer surfaces of the pipe is h1 = 40 W/m2. K and h2 = 15 W/m2 . K. Determine the rate of heat loss if the length of the pipe is 10 m. Also determine the temperature at inside, intermediate and outer surfaces.
