Trying to cram valves into small, tight spaces is a common mistake. Globe valves, in particular, have very high pressure losses (typical (L_e/D) of 340). Installing swing check valves in vertical pipe runs can also cause operational problems.
The most accurate method for calculating frictional pressure drop in both laminar and turbulent regimes is the : Trying to cram valves into small, tight spaces
ASME B31.3 specifies two types of pressure testing: The most accurate method for calculating frictional pressure
To truly master this module, you don't just need a document to download—you need to understand what that document should contain. Whether you are looking for a primer on the ASME B31.3 code or trying to brush up on the Darcy-Weisbach equation, this post breaks down the core concepts of Module 3 and guides you on where to find the best resources.
