Web4000), the friction factor, λ depends upon the Reynolds number (R) and on the relative roughness of the pipe, k/D, where, k is the average roughness height of the pipe. The … WebWe then find the absolute roughness by dividing the relative roughness(ϵ) by the pipe diameter(D). For a smooth steel pipe we have relative roughness = 0.000061m. For a …
WebThe pipe diameter is 10 cm and the pipe relative roughness is zero. Fluid density is 1 kg/L and viscosity is 1 cP. [Pg.93] For laminar flow (Re < 2000), generally found only in circuits … WebSep 19, 2006 · Moody (1944) prepared a relative-roughness chart for a number of common piping materials. Relative roughness provides a simple means for estimating friction factors to be used in computing the friction-pressure losses in piping systems. An accurate determination of the frictional fluid-pressure drop in pipes is required for design purposes.
