Explore the effect of insulation thickness on the heat loss q and the temperature of the insulation outer surface T5,2 for a steam pipe of 0.05-m outside diameter that is insulated with a layer of calcium silicate. The temperature of the steam fixed at 600 K and the outer surface is exposed to an airflow (T=30C) that maintains a heat transfer coefficient of h = 85 W/m.K, which includes the effects of radiation. where r= 0.025 m and r2 is a variable (0.025 < r2 < 0.50 m). Compute and plot the heat loss and outer surface temperature T5,2 as a function of the insulation thickness.
