Question

Two streams of air are mixed in a steady-state process. Assume air is an ideal gas with a constant heat capacity Cp=7R/2. Stream A: 0.167 mol/s, 250K, 1 bar Stream B: 0.833 mol/s, 310K, 1 bar Stream C: 1 bar (A and B going to the right into tank, and C going to the right out of the tank) a) What is the temperature of the stream leaving the tank if the process is adiabatic? b) What is the rate of entropy generation within the tank if the process is adiabatic? c) If we duplicated the stream conditions (temperatures, pressures, and flowrates) with an internally reversible process, what is the maximum rate at which work could be obtained? If desirable, you are permitted to transfer heat to the surroundings at the surroundings' temperature of 295 K.
