Pdf Exclusive — Module 3 Process Piping Hydraulics Sizing And Pressure Rating
Here’s a review written as if from a professional engineer or piping designer who has just completed the module:
- hf = Head loss (feet or meters)
- f = Friction factor (derived from Moody’s chart or Colebrook equation)
- L = Pipe length
- D = Internal pipe diameter
- v = Fluid velocity

Process Piping
The dance of is one of balance—a calculated harmony between the violent energy of moving fluids and the structural integrity of the steel that contains them. In Module 3, we move beyond simple transport and into the architecture of safety. The Physics of Sizing: The Velocity Constraint Here’s a review written as if from a
| Fluid Service | Economic Velocity (ft/s) | Erosion Velocity Limit (ft/s) | | :--- | :--- | :--- | | Saturated Steam | 80 – 120 | 150 | | Superheated Steam | 100 – 160 | 200 | | Pump Discharge (Water-like) | 8 – 12 | 15 | | Pump Suction (Water-like) | 2 – 4 | 6 | | Gas (Low Pressure) | 40 – 60 | N/A (Check DP) | hf = Head loss (feet or meters) f
