WebApr 3, 2024 · Lnewqban said: In practical terms, the coefficient is expressed only as a number. To expand/generalize, by definition a coefficient is a unitless multiplication factor, like a percentage. For example, a friction coefficient is a percentage/fraction of normal force "converted" to friction. Similarly, a flow coefficient is a fraction of velocity ... WebFlow factors are introduced for flow modification; ϕ x and ϕ y are pressure flow factors, and ϕ s is the shear-flow factor. The additional term, (U 1 –U 2)R q ϕ s /2, shows the flow due to surface roughness. For smooth surfaces bounding the lubricant film, R q is 0 and so is the additional flow.
