The calibrated flow nozzles and extensive instrumentation is required for new turbines whereas for the turbine upgrade existing flow nozzles can be used. However, inspections will be required. A reduced number of calibrated instruments is also specified. Corrections can be used to assist in the evaluations since the reference is made to the pre-upgrade turbine. Improvements are sometimes measured in Btu/kwhr or Kj/kwhr.
