👉 A plane fluid, also known as an incompressible fluid, is a type of fluid that can be described as flowing in two dimensions without any change in density across the flow. This means that the fluid's density remains constant regardless of the direction of flow or pressure variations within the fluid. Plane fluids are typically characterized by their ability to move smoothly and predictably, making them fundamental in fluid dynamics for modeling phenomena such as water flow in pipes, ocean currents, and atmospheric flows. The behavior of plane fluids is governed by equations like the Navier-Stokes equations under certain simplifying assumptions, which describe how velocity, pressure, density, and temperature evolve over time and space.
