Tests of a proposed friction-factor equation have shown it to be accurate for calculating pressure loss in turbulent flow for a pipeline transporting a non-Newtonian fluid, such as most crude oils and ...

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 ...

If there are no shear stresses present, there is no fluid deformation, and the behavior of a fluid is described by the bulk modulus relating the pressure and the compression strain. In the presence of ...

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 ...

The Navier-Stokes equations capture in a few succinct terms one of the most ubiquitous features of the physical world: the flow of fluids. The equations, which date to the 1820s, are today used to ...

The team’s theoretical calculations were largely supported by the results, and showed it’s all about the viscosity. Water reached the 90 percent mark in only a few seconds. Meanwhile, cold maple syrup ...

Scientific progress is not usually straightforward. Researchers pursue and abandon lines of inquiry. Results languish. Theories take decades to cohere. But sometimes the accumulation of scientific ...
