This article presents a new approach to determining the viscosity of Newtonian fluid. The approach is based on the analysis of the secondary Dean flow in a curved channel. The study of the flow patterns of water and aqueous solutions of glycerin in a microfluidic chip with a U-microchannel was carried out. https://www.ealisboa.com/deal-find-Orca-Vape-x-Suicide-Mods-Stubby-MTL-Conversion-Kit-huge-savings/
