Fluid friction formula
WebFor calculating liquid friction losses in a physical pipe of any material, we use the Darcy Weisbach equation and the Haaland formula for calculating friction factor. (Haaland, SE (1983). "Simple and Explicit Formulas for the Friction Factor in Turbulent Flow". Trans. ASIVIE, J. of Fluids Engineering 103: 89–90.) WebMar 28, 2024 · The Darcy Weisbach equation is used to determine the pressure drop across a pipe for a fluid. Mathematically this is: ΔP = (f × L × V² × ρ) / (2 × D) where P is pressure, f is friction factor, L is pipe length, V is flow velocity, D is pipe diameter, and ρ is the fluid density. How do I find pressure drop?

WebWhether a flow is laminar or turbulent depends of the relative importance of fluid friction (viscosity) and flow inertia. The ratio of inertial to viscous forces is the Reynolds number. Given the characteristic velocity scale, U, and length scale, L, for a system, the Reynolds number is Re = UL/ν, where ν is the kinematic viscosity of the fluid.
