Plumbing Water Supply Pipe Sizing Calculator

Screen actual supply pipe SKUs under caller independently verified matched pressure/length/material capacity and measured peak supply flow; no inferred nominal diameter velocity, universal code table or hydraulic safety.

Description

Supply-pipe candidates must be compared at the same available pressure and allowed loss.

Supply-pipe candidates must be compared at the same available pressure and allowed loss. Capacity entries are caller evidence rather than inferred pipe hydraulics.^[1]

The returned values include Caller compatible candidate ids, Signed candidate capacity margins liters minute. The How section below explains the calculation, input rules and interpretation.

When to use Plumbing Water Supply Pipe Sizing Calculator

Use Plumbing Water Supply Pipe Sizing Calculator when you need to evaluate the supplied records under the calculation and evidence rules below. No pressure-loss model, minimum diameter or plumbing-code approval is inferred.

Prepare measured flows, pressures, temperatures or inventories with consistent units. For catalog tools, use independently verified capacities at the stated operating conditions and supply the explicit design demand.

How to use Plumbing Water Supply Pipe Sizing Calculator and understand its results

Prepare measured flows, pressures, temperatures or inventories with consistent units. For catalog tools, use independently verified capacities at the stated operating conditions and supply the explicit design demand.
Enter callerSupplyPipeSkuIds, callerVerifiedMatchedSupplyCapacityLitersMinute, callerMeasuredPeakSupplyLitersMinute using the field table and calculation rules, then run the tool.
Read callerCompatibleCandidateIds, signedCandidateCapacityMarginsLitersMinute. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
callerSupplyPipeSkuIds	Caller supply pipe sku ids	list of string	Required
callerVerifiedMatchedSupplyCapacityLitersMinute	Caller verified matched supply capacity liters minute	list of number	Required
callerMeasuredPeakSupplyLitersMinute	Caller measured peak supply liters minute	number	Required

Enter aligned nonempty unique nonblank pipe IDs and nonnegative capacities plus nonnegative demand. Return every candidate meeting demand inclusively, in input order, and all signed margins.

margin=capacity−demand; eligible=margin≥0

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
callerCompatibleCandidateIds	Caller compatible candidate ids	list of string
signedCandidateCapacityMarginsLitersMinute	Signed candidate capacity margins liters minute	list of number

Limitations and assumptions

No pressure-loss model, minimum diameter or plumbing-code approval is inferred.

Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods

Use Plumbing Storm Drain Size Calculator: Storm-drain capacities depend on matched slope and hydraulic conditions. A caller catalog screens all candidates against design flow. For a complementary task, use Plumbing Drain Pipe Sizing Calculator: Drain-pipe capacities depend on matched slope and roughness. Peak waste demand can screen a verified catalog directly.
