The evaluation of the sidewall friction could be inconvenient in the implement of the Vanoni-Brooks sidewall correction procedure.Using the Colebrook-White equation and Nikuradse's pipe friction data,two explicit formulae are developed in this note for finding the sidewall friction factor.They are applicable for various sidewalls that are either hydrodynamically-smooth or rough,or in the transitional regime.
