... and carbon dioxide gases. When a joint is adjusted the joint capsule is stretched and the joint volume is increased by as much as 15-20%. This creates a partial vacuum and the gas rapidly releases due to the pressure change. (Similar to Boyle's Law, 1662). The gas takes about 20 minutes to return to ...

... In these notes, we use the divergence theorem to show that when you immerse a body in a fluid the net effect of fluid pressure acting on the surface of the body is a vertical force (called the buoyant force) whose magnitude equals the weight of fluid displaced by the body. This is known as Archimede ...

Fluid thread breakup
Fluid thread breakup is the process by which a single mass of fluid breaks into several smaller fluid masses. The process is characterized by the elongation of the fluid mass forming thin, thread-like regions between larger nodules of fluid. The thread-like regions continue to thin until they break, forming individual droplets of fluid.Thread breakup occurs where two fluids or a fluid in a vacuum form a free surface with surface energy. If more surface area is present than the minimum required to contain the volume of fluid, the system has an excess of surface energy. A system not at the minimum energy state will attempt to rearrange so as to move toward the lower energy state, leading to the breakup of the fluid into smaller masses to minimize the system surface energy by reducing the surface area. The exact outcome of the thread breakup process is dependent on the surface tension, viscosity, density, and diameter of the thread undergoing breakup.
