A process flow diagram (PFD), also known as a flowsheet, is a type of flowchart used by chemical and process engineers to illustrate highlevel processes. You should create your process flow diagram so that it focuses on major plant processes and not show minor details.

We can also make use of the Computer Aided Design (CAD) technology or flow chart software to enhance our process flow diagram skills.
A loan transaction starts with a positive cash flow when the loan is received and continuous with negative cash flows for the pay offs. upward arrows positive cash flow (receiving the loan) downward arrows negative cash flow (pay off) The Present Value of the cash flows can be calculated by multiplying each cash flow with a Discount Rate.

A Process Flow Diagram (PFD) is a type of flowchart that illustrates the relationships between major components at an industrial plant. It''s most often used in chemical engineering and process engineering, though its concepts are sometimes applied to other processes as well. It''s used to document a process, improve a process or model a new one.
This workflow describes how to design a P&ID drawing. When you place components and lines in your P&ID drawings, each component contains data that links to the Data Manager. In the Data Manager, you can view data reports, export them to a spreadsheet or a comma separated values (CSV) file, and import them back into the program.
