Arguments

re

Reynolds number

Returns Darcy friction factor f , dimensionless.

Possible Errors

Nikuradse-Reichert friction factor only valid for Re > 1e4

The given Reynolds number is out of range.

Nikuradse-Reichert friction factor only valid for e/D > 0.01

The given pipe roughness/diameter fraction is out of range.
