Molecular formula :
nature : unit time to flow through the pipeline section of a fluid quality. A symbol W said its SI system of units kg / s. Flow velocity and the quality of the relationship between W S ρ = u, u-for the fluid velocity, m / s; Ρ for fluid density, kg/m3; S-sectional area of the pipeline, m2.
