A.Derive the following relations for an actual cooled gas turbine stage:

(a) Lost work


(d) Loss of stage efficiency due to cooling




C
ª heat rejected/stage work


(e) Small stage efficiency


B.(a) Draw a sketch of the two-stage axial flow compressor with inlet guide vanes.


(b) Draw curves indicating the variation of static pressure, temperature and absolute velocity through this compressor.


(c) Why does a compressor stage have a lower efficiency and loading factor compared to an equivalent turbine stage?
