SSC SSC JE Mechanical 2025 Mock Test Series (Paper 1 & Paper 2) Power Engineering Steam Turbine Nozzle and Diffuser
The nozzle efficiency is defined as the ratio of:
1
the actual enthalpy drop to the isentropic enthalpy drop between same pressure
2
the isentropic enthalpy drop to the actual enthalpy drop between same pressure
3
the actual exit velocity to the exit velocity when flow is isentropic between same pressure
4
the exit velocity when flow is isentropic to the actual exit velocity between same pressure
