Which outcome occurs when the working fluid reaches supercritical phase in a Rankine cycle?

💡 Explanation

If a fluids is above its critical point the properties are harder to optimise, and it won't undergo phase change, making steam's latent heating capability impossible. Therefore, the isentropic turbine efficiency sharply decreases for the system, because effective expansion relies upon condensation rather than property change alone.
