Hydrostatics · 2D
Hydrostatic Forces on Submerged Surfaces
Explore pressure distributions, resultant forces, centres of pressure, and force components on plane and curved surfaces.
Open laboratoryEPFL · STREEM
Interactive, equation-based tools for exploring the principles of fluid mechanics and hydraulic engineering.
Each laboratory is designed for class demonstrations, guided exercises, and independent study. Values shown in the tools are calculated from the governing equations as controls change.
