3.2.24 cw_romeo_royo_monzon - Romeo-Royo-Monzon friction factor

f = cw_romeo_royo_monzon(d,e,re)

Calculate the Romeo-Royo-Monzon 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

Romeo-Royo-Monzon diameter is <= 0

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