A viscous fluid has a high resistance to flow and experiences significant internal friction, while an inviscid fluid has no internal friction and can flow freely without resistance.
A compressible fluid is one that can change in volume when subjected to pressure, while an incompressible fluid maintains a constant volume even when subjected to pressure.
The mass of a fluid is a measure of its inertia, or resistance to changes in motion. A higher mass fluid will require more force to accelerate or change direction compared to a lower mass fluid.
Understanding the behavior of fluids is crucial in many scientific and engineering fields, such as aerodynamics, hydrodynamics, and materials science. By studying the properties of fixed mass fluids, we can better predict and control their behavior in various applications.
No, a fluid can only exhibit one type of behavior - either viscous or inviscid. However, some fluids may exhibit a combination of both behaviors under different conditions, such as being viscous at low velocities and inviscid at high velocities.
