Figure 3.2. Generalized clean room design. Entry of personnel occurs via changing rooms, where the operators first remove their outer garments and subsequently put on suitable clean room clothing (see e.g. Figure 3.3). All raw materials, portable equipment, etc. enters the clean room via a transfer lock. After being placed in the transfer lock, such items are sanitized (where possible) by, for example, being rubbed down with a disinfectant solution. They are then transferred into the clean room proper, by clean room personnel. Processed product usually exits the clean room via an exit transfer lock and personnel often exit the room via a changing room separate from the one they entered (in some cases, the same changing room is used as an entry and exit route). Note that, in practice, product may be processed in a number of different (adjacent) clean rooms...

If it is impossible to design entries as self-explanatory, other measures such as detailed SOP and Help Pile should be generated. 

Fluid mechanics is also important in the design of electrolytic plant in other ways. First, the pipework between cells and between the cells and other units must be designed to minimize pumping costs. This requires the correct choice for the diameter of the pipework and the avoidance of unnecessary pressure drops caused by obstructions or restrictions, incorrectly designed entries, sharp turns or rapid changes in pipe diameter. More importantly, however, the electrochemical engineer must pay particular attention to the fluid entry into the cell and ensure that there are no dead zones and that the flow becomes uniform as quickly as possible. This requires the correct design of the distributor. 

Design entry in a high-level synthesis system is an algorithmic description written in a common programming language (like PASCAL or FORTRAN), or by a special purpose hardware description language (HIX), such as ISPS, DSL or VHDL.

As computers became more plentiful and more powerful, design entry tools and design visualization tools became available. Text editors and timesharing systems enabled a user to edit the SPICE description as a text file and interactively simulate the circuit. The introduction of graphic display terminals and output devices such as low-cost plotters enabled the Simula-tion results to be displayed in a visual and hence easier to comprehend manner. Even today, nearly 30 years on, SPICE and variants of SPICE are still widely used in the simulation process.
