Carbon-dioxide at 100 kPa, 25oC enters an adiabatic mixing chamber with a mass flow rate of 1 kg/s is mixed with hydrogen entering at 100 kPa and 25oC. Plot the entropy generated per unit mass of the mixture (sgen) as a function of mass fraction of hydrogen in the mixture (vary x from 0 to 1). (b) Repeat the plot with entropy generation expressed on the basis of unit mole (1 kmol) of the flow and mass fraction replaced with mole fraction.
