Which efficiency loss commonly occurs when a transcritical Rankine cycle operates?

💡 Explanation

Non-isentropic turbine expansion increases when operating transcendentally because the fluid properties change more drastically across the turbine, causing greater entropy generation, leading to lower efficiency; therefore, expansion losses increase rather than constant losses elsewhere.
