A composite spherical shell of inner radius r 1 = 0.25 m is constructed from lead of

Question:

A composite spherical shell of inner radius r₁ = 0.25 m is constructed from lead of outer radius r₂ = 0.30 m and AISI 302 stainless steel of outer radius r₃ = 0.31 m. The cavity is filled with radioactive wastes that generate heat at a rate of q = 5 X 10⁵ W/m³. It is proposed to submerge the container in oceanic waters that are at a temperature of Try. = 10°C and provide a uniform convection coefficient of h = 500 W/m² ∙ K at the outer surface of the container. Are there any problems associated with this proposal?
