ASME B31.3 (Process Piping) is the international standard governing the design, materials, fabrication, assembly, inspection, and testing of piping systems for process plants. Pressure-Temperature Ratings (ASME B16.5) ) and is calculated implicitly using the ,
Is the flow regime correctly identified (especially for viscous liquids)?

Choosing a pipe that is too small leads to excessive pressure drop and noise, while a pipe that is too large increases material and support costs. Velocity Limitations Pressure-Temperature Ratings (ASME B16
