Designing an optimal piping network requires analyzing potential fluid dynamics hazards alongside baseline sizing equations. Avoiding Cavitation in Pumps
Losses from fittings (elbows, tees, valves). Calculated using equivalent lengths ( Lecap L sub e ) or the K-factor method: 3. Piping Sizing Principles
Module 3 generally focuses on the relationship between fluid flow, pipe geometry, and pressure integrity. The objective is to ensure that process fluids are transported efficiently (hydraulics) within a conduit that can withstand the internal forces (pressure rating) and is economically sized (sizing).

Fluid particles move in parallel layers. Transition Flow (2000 < Re < 4000).
This report covers hydraulic fundamentals for process piping, methods for sizing pipes and selecting fittings, and establishing pressure ratings for components and systems. It is written for engineers and technical staff designing or evaluating industrial process piping (fluids and slurries, single-phase liquids and gases). Assumed background: undergraduate fluid mechanics and piping fundamentals.
