Final answer:
A P&ID shows the different pieces of process equipment in an area and the system that connect them.
Step-by-step explanation:
A P&ID shows the different pieces of process equipment in an area and the system that connect them. It provides a graphical representation of a process system, including equipment, instruments, and piping. P&IDs are commonly used in industrial settings to help engineers and operators understand the layout and functionality of a process.
For example, a P&ID for a chemical manufacturing plant might show equipment such as reactors, distillation columns, pumps, and compressors, as well as the piping and valves that connect them. It provides a detailed overview of the process system and helps to ensure efficient and safe operation.
By representing the equipment and system connections, a P&ID helps engineers and operators to visualize and understand the process, troubleshoot issues, and make informed decisions.
