Schema theory posits that all knowledge is organized into units or frameworks, known as schemas, which help individuals understand and interpret information by providing a structure for experiences and expectations. These schemas are dynamic, evolving with new information and experiences, and play a critical role in cognitive processes such as memory, perception, and learning.
Fluid mechanics is the branch of physics that studies the behavior of fluids (liquids and gases) and the forces acting on them. It is fundamental in understanding phenomena in engineering, meteorology, oceanography, and biology, where fluid flow is crucial.
Non-steady state flow refers to a fluid flow condition where the velocity, pressure, and other flow properties change with time at any given point in the flow field. This is in contrast to steady state flow, where these properties remain constant over time, making non-steady state flow more complex to analyze due to its time-dependent nature.
