spherical vessel

A spherical vessel used as a reactor for producing pharmaceuticals has a 10-mm-thick stainless steel wall (k = 17 W/m ∙ K) and an inner diameter of l m. The exterior surface of the vessel is exposed to ambient air (T∞= 25°C) for which a convection coefficient of 6 W/m2 ∙ K may be assumed.

 

(a) During steady-state operation, an inner surface temperature of 50 C is maintained by energy generated within the reactor. What is the heat loss from the vessel?

(b) If a 20-mm-thick layer of fiberglass insulation (k = 0.040 W/m ∙ K) is applied to the exterior of the vessel and the rate of thermal energy generation is unchanged, what is the inner surface temperature of the vessel?
