Piping Systems FluidFlow3 - Liquids, Incompressible Fluid Flow
Engineers using FluidFlow3 can determine the pressure, flow, temperature, and phase state at any point within their pipe systems. Any type and any size of piping system can be modelled. Real piping systems often contain many different types of components and fittings.
FluidFlow3 can model any component (fluid equipment item) you are likely to come across, these include: boosters (positive displacement and centrifugal types), valves (including 3-way), flow controllers, pressure sustainers, pressure reducers, differential pressure controllers, check and non return valves, orifice plates, reducers & expanders, venturi tubes, inline nozzles, filters, packed beds, cyclones, centrifuges, labyrinth seals, pipe coils, relief valves, bursting disks, shell & tube exchangers, plate exchangers, auto-claves, knock-out pots, as well as rigorously modelling junctions (tees, wyes, bends, & crosses). For items not covered by the above you can define your own.
For liquid (incompressible flow) calculations, FluidFlow3 solves the fundamental conservation equations of mass, energy, and momentum. Solution of the energy and momentum equations for an incompressible fluid results in:

The example opposite shows the main take off line for tanker loading from a LNG storage tank facility.
FluidFlow3 solves continuity, momentum and energy equations iteratively to arrive at an accurate solution. Phase states and physical properties are estimated at each point in the network. Solutions are valid for all flow regimes.
As well as modelling the liquid lines, FluidFlow3 can also model the vapor lines to the external compressor.
