Question

state the law's of fluid friction for turbulent flow​

Answer 1

Answer: Poiseuille's law applies to laminar flow of an incompressible fluid of viscosity through a tube of length and radius . The direction of flow is from greater to lower pressure. Flow rate is directly proportional to the pressure difference , and inversely proportional to the length of the tube and viscosity of the fluid.

Explanation:

Answer 2

In contrast to laminar flow, in which the fluid moves in smooth layers or channels, turbulent flow is a type of fluid (gas or liquid) flow in which the fluid experiences random fluctuations or mixing.

Laws of fluid action:

• These are the fluid friction laws:
• First law: As the area of contact between the surface and the fluid rises, so does the fluid friction.
• Second law: As the substance's velocity gradient grows, so does the fluid friction.
• Layers of a viscous fluid might encounter friction when they move in relation to one another, which is referred to as fluid friction.
• A lubricating fluid separates two solid surfaces in lubricated friction, a type of fluid friction.
• The friction of a moving item is inversely proportional to the normal force and runs perpendicular to it.
• The type of surface the thing comes into touch with determines the amount of friction it experiences.
• As long as there is a point of contact, friction does not depend on the area of contact.
