3.2.35 cw_blasius - Blasius friction factor
f = cw_blasius(re)

Calculate the Blasius approximation of the Colebrook-White equation.

Arguments

re

Reynolds number

Returns Darcy friction factor f , dimensionless.

Possible Errors

Blasius friction factor only valid for 2100 < Re < 1e5

The given Reynolds number is out of range.

Blasius diameter is <= 0

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