What causes friction between fluids and how does it affect the flow of the fluids?
Friction between fluids is caused by the interaction of molecules within the fluid. This friction can slow down the flow of the fluids, making it more difficult for them to move smoothly. It can also create turbulence and resistance, which can further impede the flow of the fluids.
What is the value of the friction coefficient between water and air?
Air and friction both being fluids, the resistive forces between them are more related to drag than friction.
Why do you say that lubricating fluids control friction?

What are the main differences between viscosity and friction?
Viscosity is a measure of a fluid's resistance to flow, while friction is the resistance encountered when two surfaces move against each other. Viscosity depends on the internal friction within a fluid, while friction is a force that opposes motion between surfaces. Viscosity is specific to fluids, while friction can occur in both solids and fluids.
Why objects moving in fluids must have special shapes?
When objects move through fluids, they have to overcome friction acting on them. In this process they lose energy. Efforts are, therefore, made to minimise friction. So , objects are given special shapes.
Do fluids exert friction?
Yes, fluids exert friction through a property called viscosity. Viscosity is a measure of a fluid's resistance to deformation or flow, causing adjacent layers of fluid to move at different velocities, creating friction between them. This frictional force is responsible for fluid flow resistance in systems such as pipes or air moving over surfaces.
Which friction force is exerted by the fluids?
The friction force exerted by fluids is typically referred to as viscous drag. This force arises due to the friction between the moving object and the fluid it is moving through. Viscous drag depends on the velocity of the object and the properties of the fluid.
The friction between moving molecules in a liquid is called?
The friction between moving molecules in a liquid is called viscosity. Viscosity is a measure of a fluid's resistance to flow, with higher viscosity fluids being more resistant to flow than lower viscosity fluids.
Does Pascal's law apply to viscous fluids?
No, Pascal's law applies to non-viscous (incompressible) fluids. Viscous fluids have internal friction that causes them to resist flow and deform. This results in a different behavior compared to non-viscous fluids governed by Pascal's law.
Viscosity is a fluids resistance to?
Viscosity is a fluid's resistance to flow. It is a measure of the fluid's internal friction and is influenced by the fluid's composition and temperature. Fluids with high viscosity flow more slowly than fluids with low viscosity.
How speed affects the friction fluids?
friction is a thing which stops a thing from going in a high speed EG: a car is goin fr0m a hill towards a deep valley. if just put a simple action then it will atomatically stop. very simple action also takes places in friction fluids.
What are the causes of fluid friction?
Fluids can be air or liquids when referring to fluid friction. A paper airplane flying through air is acted on my by friction of the atmosphere. A submarine or ship moving below or above the sea is affected by the fluid friction of water. This because matter rubbing against matter cannot do so without resistance from friction.
