Rugosity — Rugosity, f r, is a measure of small scale variations or amplitude in the height of a surface,:f r = A r/A gwhere A r is the real (true, actual) surface area and A g is the geometric surface area. [GoldBookRef|title=roughness factor (rugosity) of … Wikipedia
Roughness — is a measure of the texture of a surface. It is quantified by the vertical deviations of a real surface from its ideal form. If these deviations are large, the surface is rough; if they are small the surface is smooth. Roughness is typically… … Wikipedia
