An equimolar mixture of O2 and N2 enters a compressor

Chapter 11, Problem 11.126

(choose chapter or problem)

An equimolar mixture of \(O_{2}\) and \(N_{2}\) enters a compressor operating at steady state at 10 bar, 220 K with a mass flow rate of 1 kg/s. The mixture exits at 60 bar, 400 K with no significant change in kinetic or potential energy. Stray heat transfer from the compressor can be ignored. Determine for the compressor

(a) the power required, in kW.

(b) the rate of entropy production, in kW/K.

Assume the mixture is modeled as an ideal solution. For the pure components:
