How to fill it
Fill the inputs. The tool shows the outputs.
On the tool screen, Calc is the working sheet. Presets stores values you reuse. Reference is the formula, assumptions, and provenance below.
Formula
ΔP = K ρ v² / 2Inputs
| Name | Unit |

Diagnose
This tool does not attach diagnose observations.
Assumptions
- Single lumped K at the stated velocity. Not a catalog of fitting K values.
Provenance
- Standard minor-loss formulation. Sum K values before entry if several fittings share one velocity.
