The effects of a baffle and chemical reaction (first-order) on liquid flow in an upright double-passage channel were studied using regular perturbation analysis. Each of the two streams has its pressure gradient. temperature and velocity. and the channel is partitioned into two channels by a thin baffle that is fully conductive and flat in shape. https://www.bekindtopets.com/mega-super-Paint-Splatter-Purple-iPad-Pro-12-9in-2020-Clear-Case-p23822-must-buy/
