Question

Generally, the larger symbols on a P ID will be _______.

1) agitators
2) vessels
3) instruments
4) bays

Answer 1

The larger symbols on a P&ID generally represent vessels such as reactors, tanks, drums, and columns, which are central to the industrial process flow.

Step-by-step explanation:

Generally, the larger symbols on a P&ID (Piping and Instrumentation Diagram) will be vessels. Vessels are significant components in a P&ID and are represented by larger symbols due to their importance in the process flow. They can include items such as reactors, tanks, drums, and columns. These components are essential for containing, mixing, and processing fluids within an industrial system. Other elements like agitators, instruments, and bays also appear on P&IDs but are usually represented with smaller symbols. Instruments, for example, are typically indicated with simpler, smaller shapes or letters and numbers that designate the type of instrument or its function.
