Viskositeetittömän
Viskositeetittömän is a Finnish term that translates directly to "viscosity-less" or "without viscosity." In physics and fluid dynamics, it refers to an idealized fluid that possesses no internal friction. Such a fluid would flow without resistance, meaning no energy would be dissipated as heat due to shearing forces.
Real fluids always exhibit some degree of viscosity, though it can vary greatly. For example, water has
The concept of an inviscid fluid, or a "viscosity-less" fluid, is a useful simplification in theoretical fluid
While truly inviscid fluids do not exist in nature, the concept of viscosity-less flow is fundamental to
