3.2.28 cw_avci_kargoz - Avci-Kargoz friction factor

f = cw_avci_kargoz(d,e,re)

Calculate the Avci-Kargoz approximation of the Colebrook-White equation.

Arguments

d

Pipe internal diameter ().

e

Pipe effective roughness .

re

Reynolds number

Returns Darcy friction factor , dimensionless.

Possible Errors

Avci-Kargoz diameter is <= 0

The given internal diameter of the pipe must be above zero.
