This report outlines a method for the calculation of the speed of
sound in natural gas and the individual components that make up
natural gas. It calculates the entropy, enthalpy and C* coefficient
for the sonic nozzels. This information is based on research that was
developed and managed by the Gas Technology Institute (formerly the
Gas Research Institute). The research indicates that the calculation
is highly accurate and is consistent with the equation-of-state used
in the AGA Report No.8, Compressibility Factors of Natural Gas and
Other Related Hydrocarbon Gases. The original work for AGA Report
No.8 was developed under the auspices of the Gas Research Institute's
Basic Fluid Properties Research Program, the AGA Transmission
Measurement Committee, the Gas European de Research Group (GERG),
members of the American Petroleum Institute (API) and the
International Standards Organization (ISO).
