Question: A cylindrical cavity of diameter D and depth L is machined in a metal block, and conditions are such that the base and side surfaces

A cylindrical cavity of diameter D and depth L is machined in a metal block, and conditions are such that the base and side surfaces of the cavity are maintained at T₁ = 1000 K and T₂ = 700 K, respectively. Approximating the surfaces as black, determine the emissive power of the cavity if L = 20 mm and D = 10mm.
