  • 1.4 Input-Output and Block Flow Diagrams —

    2017-12-2 · An input-output diagram is the simplest form of flow diagrams used in industry. Input-output diagrams consist of one block with the inputs coming in one end and the outputs going out the other. The next step in designing a chemical process is constructing a block flow diagram (BFD). A BFD is similar to an input-output diagram except a BFD has multiple blocks.
