Which outcome reduces power output during a turbine cycle?

💡 Explanation

Increased back pressure lowers the Rankine cycle efficiency because the turbine has to work harder against a higher exhaust pressure, therefore decreasing the overall shaft work rather than increasing power as other options suggest under optimal condition.
