What is the efficiency of an organic Rankine cycle?
The efficiency of current high temperature Organic Rankine Cycles does not exceed 24%. Typical steam Rankine cycles show a thermal efficiency higher than 30%, but with a more complex cycle design (in terms of number of components or size).
How do you calculate the efficiency of a Rankine cycle?
Formulas related to Rankine cycle –
1
Heat Addition(qa)=h1−h4.
2
Heat Rejection (qr)=h2−h3.
3
Work done by Turbine (wt)=h1−h2.

What is the actual efficiency of Rankine cycle?
Real Rankine cycle (non-ideal)
In particular, the efficiency of the steam turbine will be limited by water-droplet formation. As the water condenses, water droplets hit the turbine blades at high speed, causing pitting and erosion, gradually decreasing the life of turbine blades and efficiency of the turbine.
What is the most efficient Rankine cycle?
We know that the Carnot cycle is most efficient cycle operating between two specified temperature limits.
