What Are High and Low Turbine Stages in a Regenerative Rankine Cycle?

[Kamuna]

TL;DR Summary

states in regenerative rankine cycle

In this cycle/ schematics I'm a bit confused what are the high turbine stage low turbine stage. Does high turbine occur in state 2? and low on state 345? I am still having difficulties in determining what state is the high turbine or low turbine stage occur please enlighten me I'm just new to the topic

What do you mean by "occur in state 2 and state 345"?
Could you show a picture of the thermo cycle linked to this system?

Show us your T-s diagram for this cycle. See examples for feedwater heater and Rankine cycle with reheat for inspiration since you have both.

here is the t-s diagram i was just confused what does this efficiency means on the turbine

Has the linked article clarified that confusion?
Could you please improve the picture to include the left side of the text?
Thank you.

Efficiencies are applied throughout the entire turbine, i.e. either 1-2' or 3-5'. On the T-s diagram, the vertical lines represent the ideal case (efficiency = 100%).
