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.markbroyard.com/best-offer-dogijiwana-tuffer-chewer-pretzel-online-flash-choice/
