The ChEMath Library is a very simple library that is capable of computing the Darcy friction factor for flow in pipes. It calculates the friction factor taking into account on which region the flow is in (laminar, transition, or turbulent).
The ChEMath Library is been released as a DLL file that can be accessed by MathCAD.
