Which outcome reduces the efficiency of a turbine engine when internal clearances increase?

💡 Explanation

Increased internal clearances within the turbine result in leakage past the blades, and decreased energy transfer because the working fluid bypasses the power extraction stage via **turbulent diffusion**, which lowers overall turbine output and efficiency. Therefore, less efficient blade performance is more likely rather than alternatives under different leakage constraints.
