In each calculation all input parameters and intermediate results are first checked to determine whether their values are within the limits defined by the Expanded range of application or not.
  • If the parameters satisfy the Expanded range they are further checked to see if they comply with at least one of the ranges A, B or C (See Table 1 in AGA Report No. 8, Part 1) and if the result is positive again then the calculation ends with no errors and no warnings and the results of the calculation are valid with an uncertainty in density generally less than 0.1 %.
  • If the parameters satisfy the Expanded range and do not comply with any of the ranges A, B or C (See Table 1 in AGA Report No. 8, Part 1), the results of the calculation are still valid but the warning bit is set in error status to warn the user that an uncertainty in density is not guaranteed to be within 0.1 %.
  • If any of the parameters do not satisfy the Expanded range, the calculation terminates with no results and with the corresponding error status flags (bits) set.

RESULTS
FE-AGA8-2017-1 calculates the parameters of a natural gas mixture for the given pressure, temperature and mole fractions of gas components. The values of operating pressure, operating temperature and mole fractions of gas componets must satisfy the Expanded range of application (see above). In case of any violation of the Expanded range limits the corresponding Error status flags will be set and the results will be cleared. If no errors where encountered the calculation procedure ends successfuly with the following parameters computed :
