Помогите плиз перевести Solving heat and materail balance в данном контексте..спасибо

The process design effort may be split into three basic steps:
synthesis
analysis and
optimization

Synthesis is the step where the structure of the flow sheet is chosen. It is also in this step that one initializes values for variables which one is free to set.

Analysis is usually made up of three steps:
solving heat and material balances
sizing and costing the equipment and
evaluating the economic worth, safety, operability etc. of the chosen flow sheet
