The inner wall of thermos bottle is at 0°C while the outer at 37°C. The space between the walls is evacuated and the walls are silvered so the emissivity is reduced to 0.10. If each wall has an area of 700 cm2, how much energy is transformed by radiation between the walls each second?
You can neglect radiation at the bottom of the plate; the bottom side of the plate has water flowing underneath it. Often, when dealing with liquids (rather than gases), one can neglect radiation because heat transfer due to convection is so much larger (liquids tend to have higher convection coefficient values than gases).
