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.

Try this example

{
  "pressure": 1000000,
  "radius": 0.5,
  "wall": 0.01
}

Accuracy and scope

Thin-wall closed-ended cylinder; excludes joints, corrosion, fatigue, nozzles and pressure-vessel design rules. Educational engineering estimate only; not structural or safety certification, equipment selection, or operating recommendations.
