Turbine isentropic efficiency compares

  • A.Work extracted with the fuel energy supplied
  • B.Turbine work with compressor work
  • C.Exit temperature with entry temperature
  • D.Actual work with the ideal work

Answer: D

Because a turbine accelerates the flow, its efficiency is typically higher than a compressor's, commonly above ninety per cent. That relative ease is one reason a gas turbine's development effort concentrates on the compressor and the combustor.
