See Answer See Answer See Answer done loading WebSimilarly, any reactor that follows the complete mixed assumption is a complete mixed reactor. In reality, there is no reactor that can meet either plug flow or complete mixed assumptions completely. Any model is an approximation of the real world. If the model is exactly the same as the real reactor then there is no need for the model.
