What is the definition of viscous drag in an oil lubricant?
If a fluid in laminar flow flows around an obstacle, it exerts a viscous drag on the obstacle. Frictional forces accelerate the fluid backward (against the direction of flow) and the obstacle forward (in the direction of flow). The viscous drag force increases linearly with the speed of the fluid.
An irregular fluid flow is what?
Irregular Fluid Flow is called Turbulent Flow! I hope this helped! :D
Can a fluid flow?
That's more or less what fluid means: something that can flow.
A fluid resistance to flow?
A fluid's resistance to flow is called viscosity.
What is the definition of steady and unsteady flow of fluid?
What is a continuous flow and unsteady flow
What is ideal fluid?
inviscid flow
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.
What is Bernouilli's equation?
it is influid dynamics, Bernoulli's principle states that for an inviscid flow, an increase in the speed of the fluid occurs simultaneous...
What is the relationship between air pressure and blood pressure?
Interestingly, according to the Bernoulli principle, when air flow is increased, air pressure is actually decreased! This same principle can be applied to any sort of fluid flow, though it the main principle applies only to a nonconducting fluid and an inviscid flow.
What is shear flow?
Shear flow is the flow induced by a force gradient (for a fluid). For solids, it is the gradient of shear stress forces throughout the body.
Why and how eddies can be formed formed in fluid despite kelvin's circulation theorem?
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.
What is pressure loss?
decrease in pressure from one point in a pipe or a duct to another point downstream of the fluid flow. It is due to frictional forces on a fluid that flow through a pipe or a duct

What are the Limitations of bernoulli's theorem?
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)

How can you define the flow of fluids?
it is so simple to define the flow of fluid . because in fluid there is no intermolecular forces and also it depends on viscosity. some liquid possess more resistance to flow like honey.. n some possess low resistance like water, honey etc
A substance whose shape can easily change is a?
Spongebob
