In a P&ID, the first letter J stands for which term?

Explanation:
In P&ID tagging, the first letter on a tag indicates the type of item or its function, and J represents a Junction. A junction is a point where piping lines meet or branch, showing where flow paths connect or split in the diagram. This helps you follow the route of a process stream and understand how different pipes are interconnected. The term Power doesn’t fit P&ID labeling for piping connections—it relates to electrical power rather than fluid flow. Jacket is used for equipment that has a surrounding thermal enclosure, not to denote a junction, and Journal isn’t a standard term used in P&ID terminology.
