The article describes a new simulation, that is, dust generated by machines during the primary processing of cotton. The cyclone can move centrifugal and gravitational forces and dust particles of various sizes acting on internal surfaces at medium speeds. The data of scientific and laboratory analyzes of dust dispersion and fractional composition are presented.

Ushbu ilmiy izlanishda neft gaz sanoati korxonalarida issiqlik almashinish apparatining gidravlik qarshiligini hisoblash usullari, suyuqlik tezligini uning massaviy sarfiga va trubalar orasida gidravlik  qarshilik ortishining Reynolds soniga bog‘liqligi holatlari yoritilgan.
