Fluid flow friction factors serve as a cornerstone in understanding and predicting the resistance encountered by fluids moving through conduits. These dimensionless parameters are essential in both ...

Editor’s note: The Basics department this month is an excerpt from the ISA book Flow of Industrial Fluids – Theory and Equations by Raymond Mulley. Some material in this section may seem self-evident ...

1.1 What is friction? Take this everyday example: when a coffee mug rests on a flat table, the kinetic frictional force is zero. There is no force trying to move the mug across the table, so there is ...

Two more methods for correcting friction effects on differential-pressure density logs from wells with high flow rates are third-party software and a nonlinear regression method. Friction affects ...
