WebSurface 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 great, the surface is rough, if they are small, the surface is smooth. Roughness is typically considered to be the high-frequency, short-wavelength component of a measured surface. WebCalculate the friction factor using the Colebrook equation. Assume absolute pipe roughness = 600 micro in. The base temperature and base pressure are 60 °F and 14.7 psia, respectively. Solution. Pipe inside diameter = 20 − 2 × 0.5 = 19.0 in. Absolute pipe roughness = 600 micro in = 0.0006 in. First we calculate the Reynolds number.
