Friction factor in a pipe

WebThe term friction loss (or frictional loss) has a number of different meanings, depending on its context.. In fluid flow it is the head loss that occurs in a containment such as a pipe or duct due to the effect of the fluid's viscosity near the surface of the containment.; In mechanical systems such as internal combustion engines, the term refers to the power … WebJul 18, 2024 · The friction factor is a function of the Reynolds number (Re = Du ρ/μ, where μ is the fluid viscosity), and its form depends on the flow regime (laminar or turbulent), and for turbulent flow, f is also a function of the pipe roughness factor (e, a length that represents small asperities on the pipe wall; values are given at the top of Figure ...

WebIn 1939, Colebrook found an implicit correlation for the friction factor in round pipes by fitting the data of experimental studies of turbulent flow in smooth and rough pipes. For hydraulically smooth pipe and the turbulent flow (Re < 10 5 ), the friction factor can be approximated by the Blasius formula: f = (100.Re)-¼. WebD is the pipe diameter or the hydraulic diameter (m). The hydraulic diameter is defined as. D= 4 x cross-sectional area / wetted perimeter. For a standard circular pipe the hydraulic diameter is the same as the actual pipe diameter. To determine the friction factor the Reynolds number needs to be calculated first. The Reynolds number is defined ...
