방법론

선언된 배관·펌프·고정 손실·수조 수면 경계 구간으로 Darcy–Weisbach와 입력된 국부 손실을 사용해 순차 HGL을 구성합니다. HGL 선별이며 속도수두 변화는 생략하고 EGL 및 TDH는 계산하지 않습니다.

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.

범위 / 제한사항

선언된 수리 특성으로 관 마찰 및 국부 손실, 순차 HGL, 압력 수두, 사용자 기준과 여유를 계산합니다.
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.
