The friction factor, f, is a dimensionless factor that depends primarily on the velocity u, diameter D, density Ï, and viscosity Î·. It is also a function of wall roughness which depends on the size Îµ, spacing Îµ' and shape of the roughness elements characterized by Îµ''.
Scale factor. The amount by which the image grows or shrinks is called the Scale Factor. Experiment with the scale factor slider to gets a feel for this idea. 1  If the scale factor is say 2, the image is enlarged so its dimensions are twice the original. 2  If it is 0.5, the image is reduced, with its dimensions half the original. 3  When the scale factor is 1, the image is the exact same size as the original.
