[answerhappygod]

Three tanks of equal volume of 4m3 each are connected to each other through tubes
of negligible volume and valves in between. Tank A contains air at 6 bar, 90°C, tank B has
air at 3 bar, 200oC and tank C contains nitrogen (N2) at 12 bar, 50oC.

Considering adiabatic
mixing, determine (i) the entropy change when valve between tank A and B is opened
until equilibrium, (ii) the entropy change when valves between tank C; tank A and tank B
are opened until equilibrium. Consider RAir = 0.287 kJ/kg.K, kAir = 1.4, RN2 = 0.297 kJ/kg. K.
