A steam pipe of 0.12-m outside diameter is insulated with a layer of calcium silicate. (a) If the insulation is 20 mm thick and its inner and outer surfaces are maintained at Ts,1 = 800 K and Ts,2 = 490 K, respectively, what is the rate of heat loss per unit length โฒ of the pipe? (b) We wish to explore the effect of insulation thickness on the rate of heat loss q โฒ and outer surface temperature Ts,2 , with the inner surface temperature fixed at Ts,1 = 800 K. The outer surface is exposed to an airflow (T[infinity] = 25ยฐC) that maintains a convection coefficient of h = 25 W/m2 ยทK and to large surroundings for which Tsur = T[infinity] = 25ยฐC. The surface emissivity of calcium silicate is approximately 0.8. Compute and plot the temperature distribution in the insulation as a function of the dimensionless radial coordinate, (r โ r1)/(r2 โ r1), where r1 = 0.06 m and r2 is a variable (0.06 < r2 โค 0.20 m). Compute and plot the rate of heat loss as a function of the insulation thickness for 0 โค (r2 โ r1) โค 0.14 m.
