Module 3 Process Piping Hydraulics Sizing And Pressure Rating Pdf Jun 2026

Equivalent length method or ( K )-factor: [ h_minor = K \cdot \fracv^22g ] Total ΔP = ( \Delta P_friction + \Delta P_minor ).

Steady-state calculations assume constant flow. However, operational changes cause transients.

Design pipes so that pressure drop is roughly 2.3 Sizing by Economical Velocity Equivalent length method or ( K )-factor: [

Where:

Calculate total ΔP (friction + minor + static). Design pipes so that pressure drop is roughly 2

hminor=K⋅v22gh sub m i n o r end-sub equals cap K center dot the fraction with numerator v squared and denominator 2 g end-fraction

Fluid flow calculation is the baseline for all piping design. Understanding how a fluid behaves inside a conduit allows engineers to predict system performance and prevent operational failures. Flow Regimes: Laminar vs. Turbulent Flow Regimes: Laminar vs

$$ h_f = \fracf L v^22 g D $$
