Inviscid flow is a type of fluid flow where viscosity effects are considered negligible. In inviscid flow, the fluid is assumed to be frictionless, meaning there is no dissipation of energy due to internal fluid friction. This simplifies the mathematical modeling of fluid motion and is often used in theoretical fluid dynamics analysis.
In inviscid fluid flow, the governing forces are inertial forces and pressure forces. In this idealized scenario, viscosity is negligible so frictional effects are not considered. The fluid motion is mainly influenced by the balance between inertial effects (related to acceleration) and pressure gradients.
The Bernoulli equation can be used in fluid dynamics to analyze the flow of an incompressible fluid along a streamline, where the fluid is steady, inviscid, and subject only to conservative forces.
Bernoulli's equation should be used in fluid dynamics when analyzing the flow of an incompressible, inviscid fluid along a streamline, where the fluid's density remains constant and friction is negligible.
The assumptions underlying Bernoulli's energy equation include steady flow, incompressible fluid, along a streamline, negligible viscous effects, and no shaft work being done on or by the fluid. It also assumes that the fluid is flowing without any heat transfer and that the flow is continuous and inviscid.
Flow can be measured using instruments such as flow meters or by calculating flow rate using the formula Q = A * V, where Q is the flow rate, A is the cross-sectional area of the flow, and V is the velocity of the fluid. Measuring devices like mass flow meters, ultrasonic flow meters, and electromagnetic flow meters are commonly used for measuring flow in various industries.
inviscid flow
In fluid dynamics, a secondary flow is a relatively minor flow superimposed on the primary flow, where the primary flow usually matches very closely the flow pattern predicted using simple analytical techniques and assuming the fluid is inviscid. (An inviscid fluid is a theoretical fluid having zero viscosity.)The primary flow of a fluid, particularly in the majority of the flow field remote from solid surfaces immersed in the fluid, is usually very similar to what would be predicted using the basic principles of physics, and assuming the fluid is inviscid. However, in real flow situations, there are regions in the flow field where the flow is significantly different in both speed and direction to what is predicted for an inviscid fluid using simple analytical techniques. The flow in these regions is the secondary flow. These regions are usually in the vicinity of the boundary of the fluid adjacent to solid surfaces where viscous forces are at work, such as in the boundary layer.

It is based on the following assumptions; (1) Steady flow (2) Incompressible flow (3) Inviscid flow (zero viscosity) (4) Flow along a streamline If a studied flow does not match these parameters, Bernoulli's theory is not applicable. (James R)
a fluid which has no viscosity
The Bernoulli equation can be used in fluid dynamics to analyze the flow of an incompressible fluid along a streamline, where the fluid is steady, inviscid, and subject only to conservative forces.
kelvin's circulation theorem describes the general case for inviscid barotropic flows - almost all real flow systems are neither. Turbulence is therefore an inevitable consequence if flow rates are large enough.

The opposite of viscosity is fluidity. It refers to how easily a substance flows or moves. A substance with low viscosity is more fluid and flows easily, while a substance with high viscosity is thick and does not flow easily.
