The changes include the implementation of a new calculation method for the pipe friction factor for Darcy-Weisbach equation. It spans the entire flow regime for laminar and turbulent flows and the transition region and is an explicit expression.
Total deviations from the Swamee-Jain equation in the turbulent regime and from the solely laminar approach 64/Re can be found in the attached image.
