A radioactive material can be considered as a sphere of ro = 0.04 m. the sphere is generating heat at a constant rate of 4x107 W/m³. The heat generated is dissipated to the environment in a steady state. The thermal conductivity of the sphere is k=15 W/m.°C and the surface of the sphere is maintained at a constant temperature of 80°C. Assuming steady one-dimensional heat transfer, (a) drive the differential equation and the express boundary conditions for heat conduction through the sphere, (b) Get a relation for the variation of temperature in the sphere by solving the differential equation, and (c) Calculate the temperature at the center of the sphere.
