Fluid & Process Data
Ve (m/s) = 0.3048 × C / √(ρlb/ft³). Lower C = more conservative (erosive/corrosive/two-phase service).
Global Notes
• Pipe ID/WT table follows ASME B36.10/19 nominal values — verify against the project piping class for critical lines.
• Gas phase uses isothermal ideal-gas density correction segment-to-segment (2-pass iteration).
• Control valve / orifice ΔP is entered manually (size separately using Cv/Cg methods).
• Friction factor: Colebrook-White (Swamee-Jain explicit form); laminar below Re 2300.
