  viscosity of natural gas
Comparisons of calculated values to the available measurements of viscosity of natural gas mixtures and of binary, ternary, and quaternary mixtures of constituent fluids are summarized to illustrate the accuracy of the predicted values.
      
The viscosity of natural gas has been evaluated by four methods: the Lohrentz-Bray-Clark (LBC), Pedersen et al.
      
The results indicate that these three methods are capable of predicting the viscosity of natural gas with an rms deviation of 3% and maximum deviations of 5 to 6%.
      


This paper proposes a set of calculation formulas of natural gas viscosity which are obtai- ned from computer fitting by use of the chart concerned.The viscosity values ealeulated by this set of calculation formulas are uniform with the values obtained from the chart. Based on this set of calculation formulas,a computer program had been worked out,which can be applied in the design calculation concerned.
