Friction factor with reynolds number
WebThe friction coefficient - or factor - of a fluid flow at laminar conditions can be calculated as. λ = 64 / Re = 64 μ / (d h u ρ) = 64 ν / (d h u) (1) where . λ = friction coefficient (non-dimensional) ... Reynolds Number - Introduction and definition of the dimensionless Reynolds Number - online calculators. Sponsored Links . WebThe friction loss for each bend is: Δ p f f = ζ x 1 2 ρ w x 2 = 673.2 P a. The total friction loss for the 10 bends is. Δ p f f = 10 ⋅ 673.2 P a = 6732 P a = 0.067 B a r. Step 6 Calculate the entire friction loss for the pipe including the fittings in this case only 90° bends but normally it also includes valves, reducers, equipment etc.
