Which outcome occurs when a closed-cycle gas turbine operates with increased turbine inlet temperature, maintaining constant pressure ratio?

💡 Explanation

When turbine inlet temperature increases at constant pressure ratio, cycle thermal efficiency increases because the average temperature at which heat is added goes up according to the Carnot principle, increasing the cycle efficiency. Therefore increased efficiency results, rather than decreased compressor work, reduced blade stress, or elevated temperature, which would involve other cycle-altering parameters or constraints.
