If you have worked with Non-Newtonian fluids or low velocity systems in AFT Fathom or AFT Impulse before, then it is likely that you have worked with the Adjusted Turbulent K Factor (ATKF) method before. The ATKF method can be used to adjust K factor data developed for turbulent flow conditions to better predict loss in the laminar f...

AFT Fathom 8 has a new and improved method for predicting system pressures that involve laminar flow or non-Newtonian fluids.  The Adjusted Turbulent K Factor (ATKF) method is used to apply corrections to pipes and components involving these special flows.  The ATKF method can be enabled on the System Data tab in the System Properties window. Clicking on the question mark next to the ATKF method will access the AFT Fathom 8 Help Content that discusses the ATKF method in detail. In September 2012, Applied Flow Technology and DuPont published a technical article for the International Pump Users Symposium that discusses...
