The setup shown in Figure 4 is an experiment that demonstrates hydrostatic forces on curved surfaces. A liquid with specific gravity of 1.30 is stored on a 30-cm diameter closed container with pressurized air. The bottom part of the container is deformed into a certain curved surface AB that has 20-cm diameter circular cross-section and hollow volume of 1200 cm³. Attached to the air layer is a U-tube manometer that (1911-1919 is connected to a 10-cm diameter piston made of a cylindrical toolgas as ts benilni od block of weight, W. The manometer fluid has a specific gravity of 10 sul mumixem er Subien 2.40. In a certain trial, the recorded magnitude of the resultant hydrostatic force on curved surface AB is 300 N. to be9q2 6 16 29140 cm bild 1191019b2003 .01 .69 SG = 1.30 .69 mig air nebi zi & trio Diano 10 cm wy SG = 2.40 al a.
