Quick guide
How to use this calculator
- Choose the analysis mode that matches the physical model before entering values.
- Enter properties, geometry, loads, states and coefficients from one consistent unit and sign convention.
- Use the intermediate outputs to audit the relationship, then retain the stated idealization before applying it.
Calculation method
Transparent engineering model
Each mode retains its named air-standard or reversible ideal relation; efficiencies remain model results rather than equipment promises.
The calculator evaluates only the declared relationship and preserves visitor-entered assumptions rather than selecting materials, factors, components or standards.
Worked example
Worked example
An ideal Otto cycle with compression ratio 10 and γ=1.4 has thermal efficiency about 60.2%.
Each mode retains its named air-standard or reversible ideal relation; efficiencies remain model results rather than equipment promises.
Supported inputs
Precision and limits
Analysis, not approval
Ideal-cycle screening only. Real-fluid properties, combustion, pressure losses, component maps, pinch limits, emissions and equipment selection remain external.
Standards and properties
Material properties, allowable values, load combinations, safety factors, correlations, manufacturer data, codes and jurisdictional requirements are not supplied automatically.
Units and precision
Use one consistent unit basis. Results retain working precision but cannot be more accurate than the entered measurements and properties.
