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 trade-offs necessary to choose a fluid involve a consideration of application requirements such as health, safety, and environmental effects, and fluid properties such as viscosity, stability, ...

Two separate correlations for predicting the isothermal compressibility of reservoir fluids and crude oils have been developed. One correlation is based on molecular weight; the other, on API gravity.

Figure 1: Seismic sequence related to the Blanco, 6.2 M w earthquake of June 2000. Figure 3: Variations in isothermal compressibility of seawater (at 3.2 wt% NaCl), with temperature and pressure 27,28 ...

Heat a liquid in a sealed tube; it seems a simple enough experiment. But it has intrigued chemists and physicists for over 175 years, probably because the results are unexpected, almost ...

Standard time-marching compressible flow solvers used extensively in the aerospace industry cannot be applied incompressible flows, as the governing equations lack a time derivative in the continuity ...
