4 topics across all disciplines.
Reading a PFD and the material balance — where every number starts
What a process flow diagram carries that a P&ID does not, how to read a stream table, why mass in equals mass out is the most useful check on a plant, and how design cases become equipment sizes.
From isometric to installed line — fabrication, erection and testing
How to read a piping isometric, why spool breaks decide what happens in the shop and what happens at height, and the test and reinstatement sequence that gets a line handed over.
Distribution and the single line diagram — the map of the electrical system
How power gets from the grid to a motor, what transformers and switchgear actually do, why protection must discriminate, and how to trace a supply on a single line diagram.
Reading a P&ID — the drawing every discipline works from
How a P&ID differs from a PFD, decoding instrument tags and bubbles, following a control loop across the sheet, and the details that decide what gets built.
