Figure 10.
Panel a presents a schematic of two connected water boxes under vacuum. The left box is suspended by a crane and is labelled minus 80 kilopascals. It has an internal width of 700 millimetres. The right box is also labelled minus 80 kilopascals and has an internal width of 750 millimetres. A label states Vaccum above the connecting line. Another label states same vacuum in both boxes. A vertical distance h is marked between the two water levels. Panel b presents the laboratory setup with two cylindrical vacuum vessels, hoses, fittings, lifting chains, shelves, and control equipment.ETHZ saturation system: (a) schematic Illustration and (b) photo of the system
