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 flow of all fluids, whether liquid or gas, will have one of three states: laminar, turbulent, and transitional. This article discusses flow principles and pressure-based flow measurement. Laminar ...

Designers should always consider flow velocity through hose and tubing to optimize performance while avoiding excessive losses or pressure spikes. This aerospace high-pressure pump installation ...

Hydraulic oil ranks high among fluids with multi-function capability. True, for sheer utility, it can’t match olive oil, which through the centuries has been used as food, lubricant, fuel, medicine, ...

Previous chapters have addressed fracture geometry, physical and geomechanical properties of single fractures, fracture detection, and the interpretation of hydraulic and tracer tests. All of these ...
