FLUIDFLOW: pipe flow and pressure drop calculator

Accurately design, analyze or troubleshoot any pipe flow system. Reduce the design time of your piping systems by 80%.

FLUIDFLOW is a modular and easy-to-use pressure drop calculator with friction and heat loss calculation capabilities. It is the only pipe flow calculator to manage in a single interface incompressible, compressible, two-phase, slurry and non-Newtonian fluid flows. With FLUIDFLOW, specify pipe flow system at a whole rather than only optimize it equipment by equipment.

Sure you will save time and money for both you and your customers!



For who


Accelerate piping design with a pipe flow calculator

Whatever the complexity of your fluid flow networks, FLUIDFLOW performs accurate friction loss calculations and automatically sizes your equipment

With FLUIDFLOW, generate your calculation reports automatically.

FLUIDFLOW is the only pipe flow software that allows pressure drop calculations for incompressible, compressible, two-phase, slurry and non-Newtonian fluids.

  • Plot pump head curves, system curve, duty point, network energy and hydraulic grade lines
  • Combine head curves for multiple pumps, flow pattern maps for two-phase flows, deposition velocity curves…
  • Identify cause of operational issues and energy saving opportunities
  • Evaluate vendor equipment performance
  • Conduct heat transfer analysis for pipes, fittings, ducts
  • Automatically detect choked flow conditions
  • Evaluate NPSHa versus NPSHr, adiabatic compression at boosters, variable speed pump control…
  • Predict likelihood of pipe blockage, particle deposition velocities, ….
Two phase fluid flow calculation with FLUIDFLOW pipe pressure drop calculator

Calculate ANY fluid pressure drop in pipe 

FLUIDFLOW is the only pipe flow software able to calculate any type of fluid or mixture in a single interface.

FLUIDFLOW calculates:

  • pressures, flows, temperatures, heat transfers,
  • linear and singular pipe pressure losses, fluid velocity at any point of the system for both single and two-phase flows.

FLUIDFLOW calculation options are based on the most universally acknowledged fluid mechanics principles and equations: Reynolds number, Bernoulli, Darcy Weisbach equations, Moody diagram, Hazen Williams, Duxbury, Wilson Addie Selgren and Clift…

The results generated by our pipe flow calculator are rigorously tested and verified on a continuous basis.

Ease piping network design with a pipe pressure drop calculator

  • Automatic equipment sizing

Accelerate your design process with automatic equipment sizing capabilities to API & ISO standards.

  • Automatic fluid phase state detection

FLUIDFLOW is the only pipe sizer to design both single and two-phase fluid systems. It automatically detects fluid phase changes within a piping network.

  • Dynamic analysis and scripting

FLUIDFLOW allows you to simulate changing conditions of your piping systems thanks to “what-if” scenarios.

  • PCF file import

FLUIDFLOW supports the import of Piping Component Files (PCF), providing interoperability with major CAD software.

Simulate pressure drops directly from isometric drawings.

With FLUIDFLOW, you make reliable piping analysis and design in less time.

A pipe pressure calculator with integrated fluids and equipment database

FLUIDFLOW software is provided with an integrated database :

  • A database including over 1200 fluids, fully defined in all phase states
  • Equipment: 800 pumps, 500 valves, …

 Don’t find what you need, you can add your own data.

With FLUIDFLOW, no need to enter manually fluid and equipment characteristics anymore. Less error, time saving, FLUIDFLOW ensures precision and efficiency in your pipe sizing projects.
