Estimate pipeline friction pressure drop and check wall thickness from diameter, velocity and length, for industrial piping and hydraulic system design.
薄壁圆筒承压公式 δ = pD/(2σ) 是压力管道壁厚设计的基础式;内径按 200 mm 计,附加 1.5 mm 覆盖腐蚀余量与负偏差,再向上取整到 0.5 mm 标准规格。
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Total pressure drop | Δp = friction + minor + static (elevation) + acceleration | Standard pipeline pressure analysis |
| Darcy pressure form | Δpf = f·(L/D)·(ρv²)/2 | Darcy-Weisbach in pressure form |
| Gas compressibility | High-pressure gas uses Z factor with Weymouth/Panhandle formulas | Gas-pipeline design practice |
| Allowable drop | Plant steam/air networks often checked at 0.05–0.1 MPa per 100 m | Industrial piping handbook |
