Steam Pipe Pressure Drop Calculator

증기 배관 압력강하 계산기 — Steam pipe pressure drop is the loss of static pressure caused by wall friction as steam flows through a pipe run.

Inputs / 입력값

Enter mass flow, pipe standard, DN/NPS, schedule, specific volume, run length, viscosity, and roughness.

Formula and assumptions / 계산식 및 가정

Darcy-Weisbach: ΔP = f × (L/D) × (ρV²/2). This straight-run quick check excludes fittings, elevation, condensate, and two-phase effects.

Worked example / 예시

Enter the expected steam flow and a 100 m run length for a selected pipe, then compare kPa loss with available pressure margin.

FAQ

Valves and fittings require a validated equivalent-length or loss-coefficient method in the final calculation.

Engineering disclaimer / 엔지니어링 고지

Engineering reference only. Verify final design against current standards, vendor documentation, actual properties, and project piping class.
