Question:

Argon at 100 kPa, 600 K enters an adiabatic mixing chamber with a mass flow rate of 1 kg/s is mixed with nitrogen entering at 100 kPa, 600 K and 1 kg/s. (a) Determine the entropy generated per unit mass of the mixture (sgen). (b) Vary the inlet temperature of nitrogen (from 200 K to 2000 K) and plot sgen as a function of temperature ratio of the incoming streams.
