Module 3 Process Piping Hydraulics Sizing And Pressure Rating Pdf 【2027】

Industry standards (ASME, Hydraulic Institute) provide velocity guidelines to avoid erosion, noise, and excessive pressure drop:

| Fluid Type | Velocity Range (m/s) | Velocity Range (ft/s) | |------------|----------------------|------------------------| | Pump suction (low NPSH) | 0.6 – 1.5 | 2 – 5 | | Pump discharge (general) | 1.5 – 3.0 | 5 – 10 | | Steam (low pressure) | 20 – 40 | 65 – 130 | | Compressed air | 10 – 25 | 33 – 82 | | Erosive fluids (slurries) | < 3 | < 10 | | Corrosive fluids | < 1.5 | < 5 |

Erosion velocity limit (API RP 14E):

[ v_max = \fracC\sqrt\rho_m ]

Where ( C ) = empirical constant (100–200 for continuous service), ( \rho_m ) = mixture density (lb/ft³). 🔍 Search tip: Include the filetype operator in
