Given: A nearly spherical (d = 4 cm) pellet of heat generating material (ġ = 6×106 W/m³). The pellet is coated with a 1.0 cm thick layer (remember that adding cm coating to the sphere will result in an outside diameter of 6 cm) with these properties p = 800 kg/m³, k = 0.15 W/mK, and cp = 1110 J/kgK. The radiation heat transfer from the surface is negligible. Convective heat transfer on the surface should be considered with the convective heat transfer coefficient of 20 W/m²K and freestream temperature of Too = = 20°C. Find: a) For a steady-state situation, make a plot of temperature as a function of radius through the spherical shell. (This is not a sketch but a plot.) b) If you were asked to solve for the temperature through the sphere, write down the equation you would use.
