Critical Velocity
Critical Velocity is the rate and direction at which the flow of a liquid through a tube changes from smooth to turbulent.The Critical Velocity is determined by a multitude of factors, but the Reynolds number is what determines whether the liquid flow through a tube is turbulent or laminar.Calculating Critical Velocity depends on several variables.
