1. The problem statement, all variables and given/known data hi there, I'm working on an annealing furnace. ingots are warmed up in the oven. I'm doing this with a finite elements method called Comsol Multiphysics. This is a pretty complex software program. Can someone please help me with this part of Comsol 2. Relevant equations it is about an aluminum alloy warmed by air at a temperature of 610 degree's alluminum has a thermal conductivity of 155 W/(m*K) the density of air is not relevant in heat transfer (because of the reynolds number) what is the heat capacity in this case? (velocity is 3.63 m/s) how long will it take to heat the ingot from 20 degrees celcius to 609 degree's celsius?!
