What is the power radiated by the sphere

Reference no: EM13296225

Consider a solid sphere of radius 15 cm, at a temperature of 68 degrees Celsius. Suppose the sphere is completely enclosed in vacuum by a vessel whose walls are kept at -22 degrees Celsius. What is the power radiated (in watts) by the sphere? For simplicity, assume the sphere and the vessel are both ideal blackbody radiators, with emissivity e = 1.
