Smooth, parallel layers (Reynolds number < 2000).

Unstable flow (Reynolds number 2000–4000).

Always kept lower (0.6 to 1.2 m/s) to prevent cavitation. Pressure Drop Considerations

The allowable pressure drop is typically dictated by the available "energy budget" of the pump or compressor. In most process plants, a rule of thumb is a pressure drop of 1–2 psi per 100 feet of pipe. 3. Pressure Rating and Wall Thickness
