Friction Coefficient at Laminar Flow

Laminar flow and friction coefficients

The friction coefficient of a fluid flow at laminar conditions can be expressed as

λ = 64 / Re (1)

where

λ = friction coefficient (nondimensional)

Re = Reynolds Number (nondimensional)

Equation (1) is only valid at laminar conditions where Reynolds Number is less than 2300. For turbulent conditions where Reynolds Number exceeds 4000, the Colebrook equation should be used to calculate the friction coefficient.
