How to use this tool

  1. Enter every input in the labeled units; use measured or independently specified properties.
  2. Check the stated model assumptions before calculating.
  3. Interpret the output as a model estimate and verify it independently for the intended application.

{
  "temperature": 300,
  "ratio": 4,
  "gamma": 1.4,
  "cp": 1005,
  "efficiency": 0.8
}

Accuracy and scope

Adiabatic ideal gas, constant cp and γ; ignores mechanical and motor losses. Educational engineering estimate only; not structural or safety certification, equipment selection, or operating recommendations.
