consider the conveyor system described in problem 7.19, but under conditions for which the conveyor is not moving and the air is quiescent. radiation effects and interactions between boundary layers on adjoining surfaces may be neglected.
A. for the prescribed plate dimension and initial temperature, as well as the precribed air temperature, what is the initial rate of heat transfer from one of the plates, in W?
B. How long, in s, does it take for plate to cool from 300oc to 150oc?
