Experimental characterization of water flow through smooth rectangular microchannels
This article presents experimental results obtained in water flows through smooth rectangular microchannels. The experimental setup used in the present study enabled the investigation of both very small length scales ( 21 – 4.5 μ m ) and a wide range of Reynolds numbers (0.1–300). The evolution of t...

The evolution of the friction coefficient was inferred from pressure drop versus flow-rate measurements for two types of water with different electrical conductivities.
