How does a fluid deform?
To deform a fluid (e.g., squeeze honey through a small hole), the molecules need to move relative to each other by squeezing past or displacing one another. This is internal friction and is what prevents a fluid from flowing. The more internal friction, the harder it is to get the molecules to move and the harder it is to force the fluid to deform.
What is internal fluid friction?
Internal fluid friction is a property of all fluids and is a result of the interactions between the molecules of the fluid.
Why can't you drink through a straw?
For instance, without internal friction, you would not be able to drink through a straw because the fluid would not be cohesive enough to enable it to be transported in such a manner. The most common illustration of internal friction is that for Couette Flow.
What is fluid friction?
Fluid friction is the force that resists motion either within the fluid itself or of another medium moving through the fluid. There is internal friction, which is a result of the interactions between molecules of the fluid, and there is external friction, which refers to how a fluid interacts with other matter.

What is the internal resistance to flow?
The internal resistance to flow is termed as viscosity. The less-dense the fluid, the greater is the ease for movement or frictional force. Fluid friction is mostly used in water slides so that we can prompt or slide down gently.
Why do objects have unique shapes?
Give a reason why objects must have unique shapes to move in fluids. According to the laws of fluid friction, it is directly proportional to the shape of an object. In order to reduce fluid friction, special forms have been designed to minimize the opposing frictional force acting on them.

Fish swim
The fish’s body experiences fluid friction in the water. Fishes’ streamlined shapes assist in reducing friction between their bodies and the water in which they travel. So they can move freely in the water.
Sailing ship
Boats and ships have narrow front and sloping sides. This is known as a streamlined shape. The streamlined shape of a boat or ship is inspired by nature, such as fish and birds, and helps to decrease friction when sailing through the water.
Shooting star
A shooting star can be observed in a clear night sky. Meteors are tiny bits of rock material floating through space. When a meteor falls from space and enters the Earth’s atmosphere, it collides with the air. Because a meteor’s speed is relatively high, it encounters a lot of friction when travelling through air.
Flying Bird
Because they fly at such a great speed, flying birds also experience friction. Despite the fluid friction provided by air, their streamlined shape allows them to fly at great speeds. Therefore, even at high wind speed, birds are capable of flying with more friction.
Aircraft
Airplanes traveling through the air are also subjected to friction. Because planes travel at such a great speed, the friction between them and the air is relatively high. The surface of the planes heats up owing to friction. The plane’s interior is insulated to keep passengers safe from the heat generated on the surface.
Hot air balloon
Drag will be observed in hot air balloons as they rise and travel through the air. As the balloon climbs, friction develops between the moving balloon and the molecules of air it encounters. Drag and gravity work against the motion of the balloon.
Walking in a storm
You may have walked in a storm before. The fast speed of the wind makes it harder to go-ahead during a storm because the fluid friction between you and the air increases while you are outside in a storm.
Why are streamlined objects important?
1) Design of the object: Objects with a streamlined design will help in the reduction of friction as the fluid molecules can easily move across the body of the object. Fishes have a streamlined body to assist them in swimming across the water. Ships have used this streamlined design for ages, mimicking nature.

What is fluid friction?
Fluid friction definition. The frictional force exerted due to fluids that resist motion within the fluid itself or resist the motion of any body moving relative to the fluid is called fluid friction. For example, When a speed boat moves in water its speed is reduced due to fluid resistance. Fluid friction experienced by a powerboat.
Why does honey move slower than water?
Because honey moves slower compared to water. It is because the molecules in any fluid face internal friction called viscosity, and this is what we call thickness or resistance to flow. Hence the molecules in honey move at a slower pace as compared to water and eventually honey seems thicker than water.
What is the process of reducing friction between two surfaces?
Lubrication is the process of reducing friction between two surfaces by adding a material called lubricant. Lubricants are always slippery or greasy as we call them. Lubricant acts as a layer between 2 sliding surfaces and converts the friction into fluidic friction.
