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 ...

An Equation of State describes the equilibrium conditions of a system in terms of values of (p,v,T) that generate the equilibrium surface of state for the substance. For an Ideal Gas the equation of ...

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 ...
