Euler's equation applied to a turbine gives the work extracted as

  • A.The axial velocity times the blade speed
  • B.The change in static pressure divided by density
  • C.Blade speed times the change in tangential velocity
  • D.The pressure ratio times the specific heat

Answer: C

The same relation governs turbines and compressors alike, differing only in the sign of the tangential velocity change. Work depends solely on blade speed and how far the rotor turns the flow tangentially, which is why both quantities are pushed as high as materials allow.
