Industrial plants rely on standard velocity and pressure drop limits to prevent issues like erosion, noise, water hammer, and high energy costs. Fluid Type Recommended Velocity Range (m/s) Target Pressure Drop (bar/100m) 0.5 – 1.2 0.05 – 0.15 Water (Pump Discharge) 1.5 – 2.5 0.4 – 1.0 Steam (Saturated) 0.1 – 0.5 Steam (Superheated) 0.2 – 0.8 Gas / Vapor (Low Pressure) 0.01 – 0.1 Gas / Vapor (High Pressure) 0.1 – 0.5 Sizing Criteria for Single-Phase Liquid Lines High velocities can cause erosion
The final step is selecting a standard commercial pipe schedule (e.g., Schedule 40, Schedule 80, Schedule 160) that meets or exceeds this nominal value. 4. Fitting and Valve Losses (Minor Losses)
Fittings, bends, tees, and valves disturb the fluid flow, creating additional pressure drops. These are calculated using either the or the Equivalent Length ( Leqcap L sub e q end-sub ) method :
: Typical liquid velocities range from 3–8 feet per second (fps) . High velocities can cause erosion, noise, and excessive pressure drop, while low velocities may lead to sediment buildup.
