nozzle efficiency

nozzle efficiency

[′näz·əl i‚fish·ən·sē]
(mechanical engineering)
The efficiency with which a nozzle converts potential energy into kinetic energy, commonly expressed as the ratio of the actual change in kinetic energy to the ideal change at the given pressure ratio.

nozzle efficiency

The ratio of actual change in kinetic energy across the nozzle to the ideal value for given inlet conditions.
