The numerical calculation of resistance characteristics was performed for a two-stage inertial stage followed by the numerical calculation of a mesh-pad stage resistance characteristics by the use of a newly built multi-layer gauze model. As a result, the numerical calculation has been completed for the total resistance characteristics of a three-stage moisture separator. On the basis of relevant requirements an optimum construction version of the moisture separator was selected and a sample unit manufactured. The measured resistance characteristics of this unit indicate that the numerical calculation accuracy has met the engineerig design requirements. All the above has made it possible to provide a simple, rapid and high-precision analytical means for the prediction of resistance characteristics during the development of a new type of moisture separators.
