Abstract According to ISO6358 which is concerned with the definition of two parameters, that is sonic conductance C and critical pressure ratio b for flow characteristics of pneumatic components, calculating methods of C & b for air tube are derived from theoretical analysis. And simulation is also conducted based on the theoretical analysis. Then a set of fitting formulae for the calculation of C & b are obtained from the simulation results by the use of LSM method. The formula are validated by experiments.
