Work ratio is = work net/turbine work.

Low because lost of work used to drive compressor.

Work ratio = (turbine work/net work).

Turbine is used to run the compressor itself.

So, work ratio is very low.

Because there will be more availability in the exit of the turbine. That's why rankine cycle is used combined with gas power plant.

70% of the power produced by the turbine is used to run the compressor itself.
