To solve the problem, we need to calculate the power of a point source of heat placed at the center of a spherical shell. The given parameters are: - Mean radius of the shell, \( R_m = 10 \, \text{cm} = 0.1 \, \text{m} \) - Thickness of the shell, \( d = 2 \, \text{cm} = 0.02 \, \text{m} \) - Thermal conductivity of the shell material, \( k = 9.5 \times 10^{-2} \, \text{kcal/m-s-°C} \) - Temperature difference between the outer and inner surface, \( \Delta T = 50 \, \text{°C} \) ### Step 1: Determine the inner and outer radii of the shell ...
