WebThis is a mechanism in fluid dynamics that controls, operates, and manages flow control of fluids of varied consistencies. This is done in industrial processes which involve the flow and transfer of a given fluid from one node to other one or multiple nodes. The fluid may be thin, viscous, semi-solid, particulate, slurry, or any other consistency. WebAgain, don't worry too much about the details of the mechanism. Our goal is to identify our nucleophile, electrophile and appreciate our electron flow and start to think about different steps of a mechanism. Nucleophilic attack is a very common one, so is loss of a leaving group. Let's look at one more organic chemistry mechanism.
