Plumbing pipe labeling inventory calculator

Calculate labels by run including both ends and total labels with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use labels by run including both ends and total labels to compare changes to your inputs. The method and limits below explain the scope.

Examples

Examples

Try the starting example

Pipe run lengths (m)
30,18,10
Maximum label spacing (m)
5
Extra labels at fittings (count)
12
Labels by run including both ends (JSON)
[7,5,3]
Total labels (count)
27

Try another scenario

Pipe run lengths (m)
[31, 18, 10]
Maximum label spacing (m)
5
Extra labels at fittings (count)

Calculation method

Calculation method

Labels by run including both ends (JSON)

Include each run end and equally spaced intermediate labels, then add entered fitting labels.

Total labels (count)

Include each run end and equally spaced intermediate labels, then add entered fitting labels.

Symbols and units
a
Pipe run lengths (m)
b
Maximum label spacing (m)
c
Extra labels at fittings (count)

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • User-supplied measurements and assumptions; Include each run end and equally spaced intermediate labels, then add entered fitting labels. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
