Turbine efficiency is a strong function of the blade speed ratio vT/CT0 and a weak function of pressure ratio, usually with high efficiency located at a large pressure ratio and a high flow rate.

Gas turbine efficiency
Turbine efficiency is the ratio of actual work output of the turbine to the net input energy supplied in the form of fuel. For stand-alone gas turbines, without any heat recovery system the efficiency will be as low as 35 to 40 per cent. This is attributed to the blade efficiency of the rotor, leakage through clearance spaces, friction, irreversible turbulence, etc.
Since exhaust gas from the gas turbine is high, it is possible to recover energy from the hot gas by a heat recovery steam generator and use the steam for process.
