Radioactive materials are to be stored in a spherical container and stored underwater to facilitate convective cooling. the spherical tank is composed of an inner shell made of lead (k=35.3 w/m/k) with an inner radius r1=0.25m and an outer radius r2=0.30m, and an outer shell made of stainless steel (k=15.1 w/m/k) with an outer radius r3=0.31m. the inner cavity is completely filled with radioactive waste that generates heat a a rate q(dot)=5x10^5 w/m^3. the water temperature is 10 c. if the tank is stored in ocean water with h=500 w/m^2/k, find the max temperature in the lead (melting point 328 c). will the lead melt?
