Steam Pipe Velocity Calculator

증기 배관 유속 계산기 — Steam pipe velocity is the average flow speed through the selected internal pipe area.

Inputs / 입력값

Enter mass flow and specific volume, then select code, DN/NPS, and schedule. The calculator uses actual internal diameter.

Formula and assumptions / 계산식 및 가정

Volumetric flow is Q = ṁv and velocity is V = Q/A, where A = πD²/4. Steam-table specific volume can feed the existing pipe calculator.

Worked example / 예시

Enter 10 t/h, choose a pipe and schedule, use the relevant steam specific volume, and compare the displayed m/s result between sizes.

FAQ

Schedule changes internal diameter and flow area. Acceptable velocity depends on pressure, quality, noise, erosion, drainage, and project criteria.

Engineering disclaimer / 엔지니어링 고지

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