Detailed Solution
Download Solution PDFExplanation:
Nozzle: It is a device that is used to increase the velocity of flowing fluid at the expense of pressure drop.
Nozzle efficiency: It is defined as the ratio of the actual enthalpy drop to the isentropic enthalpy drop at the same pressure.
\(\eta_{nozzle}=\frac{\Delta H_{Actual}}{\Delta H_{Isentropic}}\)
Factors affecting nozzle efficiency:
- Material of the nozzle
- Shape and size of nozzle
- Divergence angle
- Nature of fluid and its state
- Velocity of fluid
- Friction
- Turbulence in the flow path.
Thus, option (3) is correct answer.
