## Homework Statement

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

## Homework 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?!
