Twenty-five animated cutaways — every unit operation on the site, plus the two hydraulics sheets that connect them. Each one shows why the unit exists, the physical mechanism inside it, how the feed becomes product and waste, and which design parameter actually governs the size of it. Every animation is driven by the same correlations as the matching design sheet — here, or in the workbook — so dragging a slider moves the picture and the numbers together.
The unit operation pages are free to everyone. A subscription opens every design sheet, and the workbook is the same sheets as a file you own. One per cent of either goes to carbon removal through Stripe Climate.

Hydraulics
Not a unit operation. Nothing is separated or transformed in a pipe or a pump — hydraulics is the conveyance between the unit operations above, and it is where a sound sizing calculation is most often undone: a line one size too small, or a suction that cavitates.
