View source: R/friction_colebrook.R
Description
The phenomenological Colebrook–White equation
(or Colebrook equation) expresses the Darcy friction factor f as a function
of Reynolds number Re and pipe relative roughness, fitting the data
of experimental studies of turbulent flow in smooth and rough pipes.
The equation can be used to (iteratively) solve for the Darcy–Weisbach
friction factor f. See more about the Colebrook–White equation at the
Colebrook–White equation
Usage
1
friction_colebrook(flow, dn, roughness, temp = 15.6)
Arguments
flow
cubic meter per second (m3/s)
dn
diameter in meter (m)
roughness
roughness in (m)
temp
temp is in °C
Value
the output from uniroot for the calculation of the
root from the ecuation of Colebrook-White
Examples
1
friction_colebrook(flow = 0.042, dn = 0.150, roughness = 1.5e-6, temp = 14.5)
