Usage: technical; thermodynamics
Examples
- The gas expands isentropically when the process is both adiabatic and reversible.
- Engineers model turbine performance by assuming the fluid flows isentropically through the blades.
- An isentropically compressed fluid maintains constant entropy throughout the compression cycle.
- The ideal pump operates isentropically, with no energy loss to friction or heat transfer.
- Thermodynamic tables often list properties for isentropically expanding steam.
