3.4
Estimate the rate of heat loss due to radiation from a covered pot of water at 95 ° C. How
does this compare with the 60 W that is lost due only to convection and conduction
losses? What amount of energy input would be needed to maintain the water at its
boiling point for 30 minutes? The polished stainless steel pot is cylindrical, 20 cm in
diameter and 14 cm high, with a tight-fitting flat cover. The air temperature in the kitchen
is about 25 ° C. State any assumptions you make in deriving your estimates
