Transcribed Image Text:Nozzle/Diffuser
A nozzle receives a fluid and guides its expansion in an orderly manner to a lower pressure with
the objective of converting some of the entering energy into kinetic energy at the exit of the nozzle. The
kinetic energy is then available to drive a mechanical device.
A diffuser is a device that increases the pressure of a fluid by slowing it down.

/kg
Steam enters an adiabatic nozzle at 1378 kPa, a velocity of 3.05 m/s, a specific volume of 0.147 m
and an internal energy of 2510 kJ/kg. The exit conditions are 137.8 kPa, specific volume of 1.099 m°/kg
and internal energy of 2263 kJ/kg. Determine:
