Here you are asked to consider a steady state device that involves one inlet and two
outlet streams. The inlet gas enters at 300K and an unknown pressure. 60% of the inlet gas
leaves in one exit stream and is at 400K; the remaining 40% leaves in the second exit at an
unknown temperature. The gas in both exit streams is at 1 bar. There is no work involved
and the device is well insulated.
What is the exit temperature of the third stream?
