Process flow diagrams (PFDs) are used in chemical and process engineering. These diagrams show the flow of chemicals and the equipment involved in the process. Generally, a Process Flow Diagram shows only the major equipment and doesn't show details. PFDs are used for visitor information and new employee training.

Functions of Flowchart Symbols. Each symbol represents a piece of the code written for the program. The start/end symbol can be used to represent either the beginning or ending of a program. The symbol for process allows you to show how the program is functioning, like when you need the program to calculate two numbers or even analyze the information.
