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

{
  "heat": 100,
  "area": 0.01,
  "contact": 1000,
  "l1": 0.01,
  "k1": 200,
  "l2": 0.02,
  "k2": 50
}

Accuracy and scope

Constant prescribed contact conductance; actual conductance depends on pressure, roughness and interstitial material. Educational engineering estimate only; not structural or safety certification, equipment selection, or operating recommendations.
