Schematic Representation of a Process
摘要
This chapter will describe the most common schematic methods for representing a process, including block diagrams, piping-and-instrumentation diagrams (P&IDs), process-flow diagrams (PFDs)Process-Flow Diagram (PFD), and electrical and logic circuit diagramsCircuit diagrams. A block diagramBlock diagram is an abstract way of representing a system in the frequency domain that allows for all the messy details to be hidden and only the essential elements to be shown.
