Isentropic Efficiency

These parameters describe how efficiently a turbine, compressor or nozzle approximates a corresponding isentropic device. This parameter reduces the overall efficiency and work output. For turbines, the value of ηT is typically 0.7 to 0.9 (70–90%). Isentropic process is a special case of adiabatic processes. It is a reversible adiabatic process.
