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

{
  "rho": 1000,
  "flow": 0.01,
  "speed": 10,
  "angle": 90
}

Accuracy and scope

Free jet at ambient pressure, negligible gravity and losses through the ideal turning vane. Educational engineering estimate only; not structural or safety certification, equipment selection, or operating recommendations.
