In the thermos shown, the innermost compartment is separated from the middle container by a vacuum. There is a final shell around the thermos. This final shell is separated from the middle layer by a thin layer of air. The outside of the final sheil comes in contact with room air. Heat transfer from the inner compartment to the nexd layer gh is by radiation only (since the space is evacuated) Heat transfer between the middle layer and outside shell is by convection in a small space Heat transfer from te outside shell to t e ar is by natural convector. The heat futom each e n orte emos must be equal, which means = =9s Find the temperatures T and T, at steady state if To 2src and T, = 20C Y1 = 10-9 [(T, + 273)"-(T, + 273)"] 9s = 1.3(T2-T3)? Hint: There are two unknown (T, and T) so we need two equations to find them. These equations are the ones given in the problem statement to ensure a steady state heat transfer process Answer: T1 = 50C T_ 43.3
