Study Notes
Heat Engine Performance Metrics
- The reversible power of the heat engine is a measure of its idealized maximum power output.
- The irreversibility rate for this process is a measure of the rate at which energy is wasted due to internal dissipations.
- The second law efficiency of the heat engine is a measure of how efficiently the engine converts thermal energy into useful work, considering both the first and second laws of thermodynamics.
