Vernon, INAndSteve Chafin Process Engineer, River City Engineering, Lawrence, KSFluid flow concerns are quite prevalent among systems that handle chemicals, either inthe liquid or the vapor state. An important parameter for characterizing the energy of thefluid flowing within a contained system, such as pipes, is Pressure . This pressurebecomes important for designing pipe sizes, determining pump requirements, andaddressing safety concerns.
