Frictional Pressure Drop in Microchannel
Details
The friction characteristics of water in a sub-millimeter scale channel were investigated experimentally. The friction factors and the critical Reynolds number were measured using water flow through circular tubes and rectangular channels. The experimental results show that the measured friction factor for water agreed well with the conventional Poiseuille (λ=64/Re) and Blasius (λ=0.316 Re^<-0.25>) equations in laminar and turbulent flow regime.
