Fluids
What is fluid?
A fluid is any substance that can flow.
what is the viscosity?
Viscosity is the resistance of a fluid (liquid or gas) to a change in shape or movement of neighbouring portions relative to one another.
What is Buoyancy?
the ability to float in a liquid or to rise in a fluid.
What is the hydraulics?
Hydraulics is a mechanical function that operates through the force of liquid pressure
What is matter?
Matter is anything that takes up space and can be weighed.
What kind of fluid is jelly?
Plastic fluid
When viscosity occurs
Viscosity arises when there is relative motion between layers of the fluid.
When is buoyancy occurs?
All liquids and gases in the presence of gravity exert an upward force known as the buoyant force on any object immersed in them.
What is main purpose of hydraulic?
The purpose of hydraulic systems is to create motion or force.
What is mass?
Mass is the amount of matter or substance that makes up an object.
what is Newtonian fluids?
A Newtonian fluid is one whose viscosity is not affected by shear rate
What factors affect viscosity?
Temperature,Pressure and Shear rate
why buoyancy is important?
Buoyancy is important in swimming because it helps the swimmer to stay closer to the surface.
what is examples of hydraulic?
rivers, and channels and their confinement by dams and tanks
What is the formula for volume?
length × width × height
What is non-Newtonian fluids?
A non-Newtonian fluid is a fluid that does not follow Newton's law of viscosity
what is high viscosity and examples?
A highly viscous fluid tends to be thick, like honey or cold maple syrup.
Examples of high viscosity include honey, tomato products, sauces, and jam.
What is example of buoyancy?
steel ships floating in the middle of the ocean
How hydraulic work?
Hydraulic systems use the pump to push hydraulic fluid through the system to create fluid power.
What is the formula for mass?
Mass = Density × Volume
What factors affect fluids?
The behavior of fluid particles is affected by factors such as inertial effects, and the velocity field of the fluid.
What is low viscosity and examples?
Low viscosity liquids are liquids that have a low resistance to flow and exhibit low internal friction.
Examples of low viscosity include water, milk, and fruit juice.
What is the examples of gravity that we see in real life?
apple falling from the tree
why hydraulic system is important
Hydraulic systems are capable of moving heavier loads as well as providing greater force than mechanical, electrical or pneumatic systems.
How is mass used in our lives?
Mass is used in our lives in two ways - as matter, and as energy.
