to mix the tank contents, they must be mounted below the liquid level. Conse-quently, they are most often mounted near the bottom to assure blending of the tank contents even at a low liquid level. The major disadvantage to side-entering mixers is a submerged shaft seal, which must operate in the process fluid. Process

when the cost of heating is a small fraction of overall process costs and when the process calls for rapid on-off heating. A detailed account of the factors to be considered when designing electrical distribution systems for chemical process plants, and the equipment used (transformers, switch gear, and cables), is given by Silverman (1964).
