Question: A spherical vessel 0.3 m in diameter is located in a large room whose walls are at 27?C (see sketch). If the vessel is used

A spherical vessel 0.3 m in diameter is located in a large room whose walls are at 27?C (see sketch). If the vessel is used to store liquid oxygen at ??183?C and the surface of the storage vessel as well as the walls of the room are black, calculate the rate of heat transfer by radiation to the liquid oxygen in watts and in Btu/h.GIVENA black spherical vessel of liquid oxygen in a large black roomLiquid oxygen temperature (To) = ??183?C = 90 KSphere diameter (D) = 0.3 mRoom wall temperature (Tw) = 27?C = 300 KASSUMPTIONSSteady state prevailsThe temperature of the vessel wall is the same as the temperature of theoxygen
