Consider a steam pipe of length L = 20 m, inner radius r = 6 cm, outer radius 12 cm, and thermal conductivity k = 20 W/m. C, as shown below 8 cm The inner and outer surfaces of the pipe are maintained at average temperatures of T = 150C and T = 60C, respectively. Obtain a general relation for the temperature distribution inside the pipe under steady conditions, and determine the rate of heat loss from the steam through the pipe.
