What is the meaning of 'secondary 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.
How many fluid ounses are in 6 cups?
48 fluid ounces. There are eight fluid ounces per cup.
What does displaced fluid mean?
As a Nurse this makes me think of fluid shifts in the body. There are many causes for "displaced fluid" or fluid shifting. Ask your doctor.
If an object 's density is greater than the density of a fluid it?
It will sink in the fluid. It will sink in the fluid.
What is bernoullis principle?
The relationship between the velocity and pressure exerted by a moving liquid is described by the Bernoulli's principle: as the velocity of a fluid increases, the pressure exerted by that fluid decreases.Airplanes get a part of their lift by taking advantage of Bernoulli's principle. Race cars employ Bernoulli's principle to keep their rear wheels on the ground while traveling at high speeds.Bernoulli's principle, physical principle formulated by Daniel Bernoulli that states that as the speed of a moving fluid (liquid or gas) increases, the pressure within the fluid decreases. The phenomenon described by Bernoulli's principle has many practical applications; it is employed in the carburetor and the atomizer, in which air is the moving fluid, and in the aspirator, in which water is the moving fluid. In the first two devices air moving through a tube passes through a constriction, which causes an increase in speed and a corresponding reduction in pressure. As a result, liquid is forced up into the air stream (through a narrow tube that leads from the body of the liquid to the constriction) by the greater atmospheric pressure on the surface of the liquid. In the aspirator air is drawn into a stream of water as the water flows through a constriction. Bernoulli's principle can be explained in terms of the law of conservation of energy (see conservation laws, in physics). As a fluid moves from a wider pipe into a narrower pipe or a constriction, a corresponding volume must move a greater distance forward in the narrower pipe and thus have a greater speed. At the same time, the work done by corresponding volumes in the wider and narrower pipes will be expressed by the product of the pressure and the volume. Since the speed is greater in the narrower pipe, the kinetic energy of that volume is greater. Then, by the law of conservation of energy, this increase in kinetic energy must be balanced by a decrease in the pressure-volume product, or, since the volumes are equal, by a decrease in pressure.
What is ideal fluid?
inviscid flow
What is inviscid flow?
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.
What forces govern the inviscid fluid flow?
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.
When can you use the Bernoulli equation in fluid dynamics?
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.

When should Bernoulli's equation be used in fluid dynamics?
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.
What is the assumptions underlying the Bernoulli's energy equation?
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.
State and define the physical characteristics associated with a fluid?
a liquid
What is the define of vacuoles?
Membrane-bound sacs that are filled with fluid.
What is the opposite of viscosity?
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.
