What does a fluid process mean?
What does a fluid process mean?
Fluid processes are continually being adapted and reformed to fit the actual needs and constraints of the situation in hand and to fulfill the overall goals of the involved actors in the best possible way.
What is the other name of fluid friction?
Fluid friction occurs between fluid layers that are moving relative to each other. This internal resistance to flow is named viscosity. In everyday terms, the viscosity of a fluid is described as its “thickness”.
What is fluid friction and examples?
Fluid friction is friction that occurs when objects move across or through a fluid. Examples: Swimming – swimmer’s body. and surface of water.
How is fluid friction Minimised?
The fluid friction or drag can be reduced are minimised by giving special shape called streamlined shape to the objects which Move through fluids like air or water . For example: 1)Cars are built with streamlined body shape to reduce air resistance or drag caused by a air.
How does fluid friction depend on speed?
The speed of the object moving through a fluid affects the amount of friction acting against the motion of the object. More the speed, more is the friction. If the object is broad, it gives more area for the friction to act on. Thus, a streamlined body structure helps to cut through the fluid and reduce friction.
What are 2 causes of friction?
Friction is a force that resists the relative motion between two objects or materials. The causes of this resistive force are molecular adhesion, surface roughness, and deformations. Adhesion is the molecular force resulting when two materials are brought into close contact with each other.
How is fluid friction minimized Class 8?
Friction can be minimized by using lubricants like oil and grease and by using ball bearing between machine parts. A substance that is introduced between two surfaces in contact, to reduce friction, is called a lubricant. Fluid friction can be minimized by giving suitable shapes to the objects moving in the fluids.
How is friction caused class 8th?
Friction is caused by the interlocking of irregularities in the surface of two objects which are in contact with each other. To move one object over the other ,we have to apply a force to overcome interlocking of the irregularities in their surfaces.
What is friction explain with an example class 8?
There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding, and rolling friction occur between solid surfaces. Static friction is strongest, followed by sliding friction, and then rolling friction, which is weakest. Fluid friction occurs in fluids, which are liquids or gases.
What does friction Class 8 mean?
Force of Friction: (i) Friction is the force which resists the relative motion of surfaces. (ii) All types of surface like solid, liquid and air offer the force of friction. It stops after moving for some distance because of friction between the surfaces of book and table. …
What is friction Class 9?
When one body makes an attempt to slide over another body, an opposing force called the force of friction arises as a reaction to the applied force, and acts in the opposite direction.
