Find the net rate of radiation 𝐻net by a pot at 34.9 ∘C that has been placed in a −19.5 ∘C freezer. The pot's surface area is 0.107 m2 and its emissivity is 0.569.

Question

Find the net rate of radiation 𝐻net by a pot at 34.9 ∘C that has been placed in a −19.5 ∘C freezer. The pot's surface area is 0.107 m2 and its emissivity is 0.569.

Answer 1

Use the equation Q rate = εσA(T⁴-T_∞⁴)

Remember to use Kelvin for T and the Boltzmann equation constant is 5.670 x 10^-8 W/m²·K⁴. Everything else is in the right units.
