APPENDIX C3: Design of Seaplanes - Elsevier.com
booksite.elsevier.comThe Archimedes Principle The principle is named after Archimedes of Syracuse (287-212 BCE), who first discovered this law. The law states that any object, entirely or partially immersed in a fluid, experiences a force of buoyancy equal to the weight of the fluid displaced by it. The law ignores surface tension (capillarity) acting on the body.
