Convert a fitting K into equivalent straight-pipe length.

Fluid & Pressure

Convert a fitting K into equivalent straight-pipe length.

App id: FLUID-20. Reference version 1.0.

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 / f

Inputs

NameUnit
Loss coefficient K1
Inside diametermm
Darcy friction factor1

Outputs

NameUnit
Equivalent length (hero result)m

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.
