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
L_eq = K D / fInputs
| Name | Unit |

Diagnose
This tool does not attach diagnose observations.
Assumptions
- f should represent the same pipe and flow as the run being estimated.
Provenance
- L_eq = KD/f using the Darcy friction factor of the connecting pipe.
