The stage efficiency ($${\eta _{\text{S}}}$$) is given by (where $${\eta _{\text{B}}}$$ = Blading efficiency and $${\eta _{\text{N}}}$$ = Nozzle efficiency)

$${\eta _{\text{S}}} = {\eta _{\text{B}}} \times {\eta _{\text{N}}}$$

$${\eta _{\text{S}}} = \frac{{{\eta _{\text{B}}}}}{{{\eta _{\text{N}}}}}$$

$${\eta _{\text{S}}} = \frac{{{\eta _{\text{N}}}}}{{{\eta _{\text{B}}}}}$$

None of these

The stage efficiency ($${\eta _{\text{S}}}$$) is given by (where $${\eta _{\text{B}}}$$ = Blading efficiency and $${\eta _{\text{N}}}$$ = Nozzle efficiency) Correct Answer $${\eta _{\text{S}}} = {\eta _{\text{B}}} \times {\eta _{\text{N}}}$$
