Presentation transcript:

Metal vs. Glass The effect of conduction in baking.

Simplifications Same amount of time to cook Same heat transfer rate Pans are the same size The temperature on the inside of the pan (touching food) is the same The effects of radiation are ignored.

Calculations Used a simple 1-D wall for calculations The radiation was neglected to see what would be required if radiation didn’t play a role Assumed the thickness (L) and heat flux were equivalent for both materials

Conclusions The aluminum temperature is almost exactly the same as the food, so the oven only needs to be at the same temperature. The required temperature on the outside of the glass grew rapidly with increased thickness. Fact: Food cooks just as quick in glass as metal. The effect of radiation is great when you are cooking with glass.
