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?

WebAug 12, 2024 · AC = Length of the whole plate. (FD) for AC = Drag Force for AC. Cf = Skin Friction Coefficient. Firstly we need to calculate Skin Friction Coefficient from the formula given. Cf = 0.074 / (Rex)^1/5. For this Rex is the Reynolds Number based on the whole length of the plate. 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.
