A hollow sphere of inside and outside radius of 3 cm and 5 cm, respectively, is electrically heated at the inner surface at a constant rate 10 W/m^2. At the outer surface it dissipates heat by convection into a fluid at temperature 100 C and heat transfer coefficient 400 W.m62-C. The thermal conductivity of the sphere material is 15 W/m-K. Determine the inner and outer surface temperatures of the sphere.© BrainMass Inc. brainmass.com March 4, 2021, 6:02 pm ad1c9bdddf
