Compressor power usually depends on the mass flow rate, compression ratio, suction conditions, slope of isentropic lines, and polytropic index.
It can be seen from Figure 4 that as the intermediate pressure increases above the critical pressure, the second-stage compression process moves quickly into the supercritical region, where the slopes of the isentropic lines are steeper than in the conventional superheated region.
