Work ratio = (turbine work/net work).

Turbine is used to run the compressor itself.

So, work ratio is very low.

Maximum power turbine is consumed by compressor itself and also air is working Media so max Power loss.

The efficiency is very low because, turbine is rotating device due to that it haves high losses.

Gas turbine's efficiency and work is minimum because less of friction but turbine fan and air.

Half and more the power produced by the turbine is used to complete motion in the compressor.

Since efficiency is a function of pressure ratio in simple gas turbine (braton, joule) cycle.

Efficiency = Output/input then,

Work Ratio = Net work of the turbine/Work of the turbine.

Digvijay singh said:   1 decade ago
Work ratio is = work net/turbine work.

Low because lost of work used to drive compressor.

Work efficiency increases by regeneration in simple gas turbine otherwise it is minimum.
