A gas mixture consists of O2 and N2. The ratio of the mole numbers of nitrogen to oxygen is 3:1. This mixture is heated during a steady-flow process from 180 to 210 K at a constant pressure of 8 MPa. Determine (surroundings @ 25 C):
1. The heat transfer, entropy generation, and exergy destruction per kmol of the mixture using ideal gas approximation (assume constant specific heats).
