0.02 to 0.2 bar per 100 meters (0.01 to 0.1 psi/100 ft) Two-Phase Flow Considerations
Rearranging this formula allows you to calculate the required inner diameter based on an acceptable target velocity:
Apply the continuity equation to find the initial inside pipe diameter. Most industrial process piping operates deep within this
Once the diameter is determined, the pipe must be rated to safely contain the internal process pressure at the operating temperature. Nominal Pipe Size and Schedule Explained | PDF - Scribd
): Characterized by chaotic fluid particles and rapid mixing. Most industrial process piping operates deep within this regime. The Continuity Equation fluid velocity limitations
): A fluid's resistance to gradual deformation by shear or tensile stress. Vapor Pressure ( Pvcap P sub v
This means decreasing the pipe diameter directly increases fluid velocity. 2. Pipe Sizing Methodology pressure drop calculations
To navigate this trade-off, engineers use established heuristics or "rules of thumb" based on decades of industry experience. These provide a starting point for line sizing.
): Use the continuity equation to find the preliminary size.
This guide covers the fundamental principles of process piping hydraulics, fluid velocity limitations, pressure drop calculations, and pipe pressure rating determinations. 1. Fundamentals of Piping Hydraulics
): Flow fluctuates between laminar and turbulent characteristics. Turbulent Flow (
