The equation of state developed for sweet/dry natural gases was used to predict the sonic velocity of pure methane and other pure systems for which data exist. In the region of interest to sonic-nozzle calculations, excellent agreement was obtained between pure methane experimental sonic velocities and the calculated sound speeds from the equation of state with agreement often better than 0.05%. At low temperatures (less than 250K) and pressures near the critical pressure of methane, significant differences between calculated sonic velocities and experimental sound speeds were found. This suggests the equation of state could be improved, if deemed necessary, for this region. To date, accurate speed of sound measurements for actual natural gas mixtures have not been made. This severely limits testing the equation of state beyond the limited amount of pure-component data until mixture data become available. A computer program was developed to predict all the important properties used in sonic-nozzle calculations.
