A new cubic molecular-based equation of state (MMM) accurately calculates pressure, volume, temperature (PVT) and vapor-liquid equilibrium (VLE) data for pure and mixed fluids. Comparisons to the ...

For fluids in thermal equilibrium, the concept of pressure, P, is familiar as the force per unit area exerted by the fluid on its containing vessel. This primary, mechanical definition of pressure ...

Developing a unified theory for liquid behaviour has long been a challenge due to the complex interactions between particles and the constantly changing dynamic disorder within liquids. Current ...

The study of phase equilibria and equations of state (EoS) in natural gas systems is pivotal for optimising extraction, processing and transportation operations. These systems demand highly accurate ...

Proceedings of the Royal Society of London. Series A, Mathematical and Physical Sciences, Vol. 213, No. 1113 (Jun. 24, 1952), pp. 214-225 (13 pages) It is suggested that, at high pressures and ...

Oil field operators can use several practical equations for calculating flow rates of natural gas through venturi gas-lift valves. For critical flow, this analysis derived such equations from a ...
