エンジニアリングの根拠

方法

宣言された配管、ポンプ、固定損失、水面境界の区間から、Darcy–Weisbach と入力局部損失を用いて連続した水理勾配線を作成します。HGL のスクリーニングであり、速度水頭変化を省略し、EGL と TDH は計算しません。

Pipe velocity = Q/A; Reynolds number = vD/ν. Darcy factor uses f = 64/Re for laminar flow and Swamee–Jain for turbulent flow.

Major pipe loss uses Darcy–Weisbach; minor loss is ΣK·v²/(2g).

The sequential profile adds entered pump head and subtracts major, minor, and fixed equipment losses. A basin water surface is an explicit downstream HGL boundary.

Elevation is reported separately; pressure head where elevation is entered is downstream HGL minus elevation.

A segment minimum HGL criterion is evaluated once at its downstream station. The optional starting minimum HGL criterion is evaluated at the starting station.

For 2,000 < Re < 4,000, Swamee–Jain is used as a screening approximation and a transitional-flow warning is reported.

範囲 / 制限事項

指定された水理特性から、管摩擦損失と局部損失、区間ごとの HGL、圧力水頭、ユーザー基準、余裕を計算します。
No transient surge, looped network solution, pump selection, system-wide NPSH, or open-channel gradually varied flow.
No hydraulic grade is inferred from process-unit names. Basin water surfaces and minimum HGL criteria must be declared.
A margin below a user criterion is flagged for review but is not classified as safe or unsafe.
This screening HGL profile omits changes in velocity head between segments. It adds entered pump head directly to HGL and does not calculate the total energy grade line or total dynamic head (TDH).
Freeboard and available driving head are not calculated. No US-unit conversion path is implemented; hydraulic inputs and outputs use SI units.
