One of the new features in AFT Fathom 9 was the ability to model equivalent lengths instead of K factors for various types of fittings. Since AFT Fathom's existence, the standard K factor loss models have been used to quantify the pressure losses across a fitting such as an elbow, a valve, etc.  One of the reasons why the K factor method is very useful is because it is broad and applicable to a wide range of different fittings.  However, the equivalent length method is also a way that engineers will typically quantify the losses through their fittings and they will...
