Viskozen tok

Viskozen pretok: stanje pretoka, v katerem je povprečna prosta pot molekul plina veliko manjša od najmanjše velikosti prereza vodnika. Therefore, flow depends on the viscosity of the gas, and viscous flow can be laminar flow or stagnant flow. 24. Viscosity coefficient: The ratio of the tangential force per unit area to the velocity gradient in the direction of the airflow velocity gradient. 25. Pochau flow: Laminar viscous flow flowing through a long circular cross-section Vmesni pretok . 26.: pretok plina skozi kanal v stanju med laminarnim tokom in molekularnim tokom . 27. molekularni tok: stanje pretoka, v katerem je povprečna prosta pot molekul veliko večja od največje velikosti prekrižanja, ki se je lahko preseglo, da je povprečna številka od pline . 28.}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}-anolekanja. Premer cevi . 29. molekularni preliv: stanje pretoka, ko plin teče skozi tankostensko majhno luknjo in je povprečna prosta pot molekul veliko večja od velikosti luknje . 30.: pretok plina, ki ga povzročajo, v pobegu, ki ga povzročajo razlike v tlaku {{12} the the Thews the Twe The The Through experience gas flow due to different temperatures and the gas transmission reaches equilibrium, a pressure gradient is generated between the two containers. 32. Molecular flow rate: The difference between the number of molecules passing through a surface from a given direction and the number of molecules passing through the surface from the opposite direction within a given time interval, divided by that time. 33. Molecular flow rate density: Molecular flow rate divided by surface area. 34. Mass flow rate: The mass of gas passing through a certain cross-section within a given time interval, divided by that time. 35. Flow rate: The volume of gas passing through a certain cross-section within a given time interval divided by that time. 36. Volumetric flow rate: The volume of gas passing through a certain cross-section under given temperature, Pogoji tlaka in časovnih intervalov, deljeni s takrat.
