The effects and influences of various operational parameters on the efficiency of mixer-settlers are thoroughly studied in this paper. One of the most important factors in designing a mixer-settler is to obtain an optimum operational extraction and overall efficiency. These two factors are dependent on various parameters such as impeller shape. size and speed of impeller. https://zckhwstbgmpv.timeblog.net/70682630/psychological-health-correlation-of-express-delivery-workers-occupational-stress-in-the-information-logistics-environment
