TECCINESS: Pressure Loss Calculation at Constant Density

This website offers numerous features for the design of your piping system.
The use of this website is free of charge.

  • Quick-Check: pressure drop calculation for straight piping according Moody-Diagram.
  • Project: up to 3 system curves and 5 pump curves.
  • Graphical evaluation: check where your system curves and pump curves meet best for your point of operation.
  • Save your project on the Download -page. You can upload and continue your project on your next visit!
  • Up to 3 system curves in a project - study the implications of different volume flows, storage levels, surface roughnesses, material values (density, viscosity) and/or different designs of piping, valves and other devices.
  • Up to 5 pump curves in a project - compare different pump types and models. Further options are pumps in series, pumps in parallel and the variation of speed.
  • Interactive PID: by clicking on valves you configure your piping system: inlet from below or above, filling from the top or the bottom, closed loop.
  • Comprehensive help pages (material values, pipe roughness, pipe dimensions, means of calculation, Converter).
