Is there a way to calculate both temperatures? I plan on modeling in Simulink but I really don't know what equations to start with.

I am setting up a system where a rectangular plate is heated by a set of heater cartridges, producing about 4000 watts. This plate is in free convection air. It is used to melt plastic at regular invervals. I am trying to model the system so we can estimate temperatures of the plate to...
