The net work of a Brayton cycle is the difference between

  • A.Turbine work output and compressor work input
  • B.Heat added and pressure ratio
  • C.Turbine entry and exit temperature
  • D.Fuel energy and exhaust energy

Answer: A

The compressor typically absorbs more than half of what the turbine produces, so the net output is a modest difference between two large numbers. That is why small losses in either component have a disproportionate effect on the useful work available.
