1. The problem statement, all variables and given/known data A hot reservoir with a temperature of 653 K is 0.7 m away from a cold reservoir with a temperature of 399 K. The two reservoirs are insulated from each other except for a rod of brass (k = 109 W/m-K) that has a cross-sectional area of 0.07 m2. The entire system is allowed to reach a steady-state condition. 1)How much energy is transferred between the hot reservoir and the cold reservoir by heat in ten minutes? 2. Relevant equations thermal current=change in temp*thermal resistance, I=ΔT/R R=|Δx|/kA 3. The attempt at a solution R=.7/(109*.07)=.091743 K/W I=(653-399)/.091743=2768.6 W for 10 minutes: 2768.6 J/S * 60 S/min * 10 min=1,661,162.16 J Sorry for the simple question, but the homework software says that answer is incorrect and I can't really see what could be wrong with such a straightforward problem, I imagine I'm missing something stupid but can't find it.
