Now that the turkey has been in the oven for quite some time, it is now time to get the gravy ready. First, you will need to put a circular aluminum sauce pan with a 12-cm diameter and a thickness of 8-mm on the stovetop and turn on the burner. Now you 120-gram mix the gravy contents with 360-grams of water. Assume that the latent heat of evaporation for gravy is similar to that of water, which is ?v=2260 KJ/Kg and that the thermal conductivity constant for aluminum is 220 J/s*m*°c
a) If the rate electric stove top has a heat transfer rate of 2.3 kW, solve for the temperature difference across the bottom of the aluminum pan.
b) Suppose the gravy reaches a boiling point at 100°C. How long will it take all of the gravy to completely “evaporate” if it behaved like water.
