Chemical Processing, 2000 Fluid Flow 1 of 8 Calculating Two-Phase Pressure DropScott S. Haraburda, PE Engineer, GE Plastics, Mt. 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. Often the fluid is flowing as both liquid and TypeThe flow type of Two-Phase liquid-gas flow can be characterized into one of seven typesshown in Figure 1.
