2. Natural gas compressibility factor (z-Factor) 2.1. Background The calculation of natural gas volume, density and viscosity at elevated pressures and temperatures requires values of z-Factor. All the Equations of State (EoS) are implicit in terms of the z-Factor; this means that the z-Fac...
We can see the effect of viscosity in a Bunsen burner flame, even though the viscosity of natural gas is small. The resistance R to laminar flow of an incompressible fluid having viscosity η through a horizontal tube of uniform radius r and length l, such as the one in Figure 5, is ...
Keywords Natural gas · Re-evaluation · Viscosity 1 Introduction We appreciate the collaboration with Professor Span, particularly when we worked together on the viscosity correlation for ethane [1]. Professor Span's group performed measurements and modeling of the viscosity of nitrogen-...
For example, water has a viscosity of 1.0 centipoise (cP), whereas the viscosity of natural gas is approximately 0.0008 cP. Viscosity has an impact on the type of flow in pipelines. The Reynolds number (discussed in Chapter 8) is a dimensionless parameter that is used to classify the type...
A reliable pure and natural gas viscosity model has been developed.A large databank consisting of more than 3800 data sets have been used to develop the model.Input parametersare pseudo-reduced temperature, pseudo-reduced pressure, gas density, and molecular weight of gases.Least square support ve...
Validity of gas viscosity equationFor hydrocarbon vapors and natural gases, input temperature T is restricted to the range 0 < T < 1000oF.For other gases, input temperature must be at least absolute zero (0 K).If the input temperature is outside the valid range, an error message is ...

A unit of measurement traditionally used to measure surface tension. May also refer to torque in viscosity measurements. FluidA fluid is a substance which deforms continuously under the application of a shear stress and can be either a liquid or gas. Kinematic ViscosityA measure of a fluid’s...
The viscosity of natural gas can be measured in a laboratory and it depends upon pressure, temperature, and composition. When laboratory data are not available, gas viscosity can be computed using available empirical data. Contrary to the liquids, the viscosity of gas increases with temperature for...
