Flux F through a surface, dS is the differential vector area element, n is the unit normal to the surface. Left: No flux passes in the surface, the maximum amount flows normal to the surface.
Consider a 1-ton block of solid iron. As iron is nearly eight times as dense as water, it displaces only 1/8 ton of water when submerged, which is not enough to keep it afloat. Suppose the same iron block is reshaped into a bowl. It still weighs 1 ton, but when it is put in water, it displaces a greater volume of water than when it was a block.
Fluid mechanics is the branch of physics concerned with the mechanics of fluids (liquids, gases, and plasmas) and the forces on them. [1]: 3 It has applications in a wide range of disciplines, including mechanical, aerospace, civil, chemical, and biomedical engineering, as well as geophysics, oceanography, meteorology, astrophysics, and biology.
In physics, physical chemistry and engineering, fluid dynamics is a subdiscipline of fluid mechanics that describes the flow of fluids – liquids and gases.It has several subdisciplines, including aerodynamics (the study of air and other gases in motion) and hydrodynamics (the study of water and other liquids in motion).
In fluid dynamics, slosh refers to the movement of liquid inside another object (which is, typically, also undergoing motion). Strictly speaking, the liquid must have a free surface to constitute a slosh dynamics problem, where the dynamics of the liquid can interact with the container to alter the system dynamics significantly.

Before you pack that carry-on bag and head to the airport, get schooled on these five essential TSA rules for a stress-free flight. From TSA liquid limit to carry-on rules, your most-pressing TSA ...
If the fluid is a liquid, depends on the Reynolds number; if the fluid is a gas, depends on both the Reynolds number and the Mach number. The equation is attributed to Lord Rayleigh, who originally used L 2 in place of A (with L being some linear dimension). [2]
The BBC added that security restrictions for liquids and laptops in carry-on luggage could be axed from mid-2024. Heathrow’s chief executive, John Holland-Kaye, told The Times: “We are slowly ...
