👉 Fluid, primarily composed of water and various dissolved substances, exhibits complex mechanisms of movement driven by several key forces. Primarily, fluid flows due to pressure gradients, where higher pressure areas push fluid towards lower pressure regions. Additionally, fluid motion is influenced by viscosity, which resists flow and depends on the fluid's properties. Surface tension and capillary action also play roles, especially in smaller scales or at interfaces with other substances. In larger systems, fluid dynamics principles like Bernoulli's equation and the Navier-Stokes equations describe how velocity, pressure, and density interact to govern fluid behavior. These mechanisms collectively result in phenomena such as laminar flow, turbulence, and the formation of vortices, all of which are crucial in understanding fluid dynamics across various applications from meteorology to engineering.
