just a A hot water pipe that is used for domestic applications of 0.12 m outside diameter is insulated witha layer of calcium silicate. If the insulation is 20 mm thick and its inner and outer surfaces aremaintained at T,1= 800 K and T32= 490 K, respectively(a)What is the heat loss per unit length (q') of the pipe?(b)Explore the effect of insulation thickness on the heat loss q' and outer surface temperatureT32 with the inner surface temperature being fixed at 800 K. The outer surface is exposed tomoving airflow (T= 25°C) that maintains a convection coefficient of 25 W/m2 K and to largesurroundings for which Taus= T= 25°C. The surface emissivity of calcium silicate isapproximately 0.9.Compute and plot the temperature distribution in the insulation material as a function of the radialrzceordinate, where n = 0.06 m and 12 has a range of (0.06< 1, <0.2 m).Compute and plot the r2 -r1heat loss as a function of the insulation thickness for 0< (12 - 1) <0.14 m. Given the thermalconductivity of calcium silicate insulation equals to 0.089 W/m.K.
