What is the best meaning of streamlined?
What is the best meaning of streamlined?
1a : contoured to reduce resistance to motion through a fluid (such as air) b : stripped of nonessentials : compact. c : effectively integrated : organized.
What is the purpose of streamlining?
Streamlining, in aerodynamics, the contouring of an object, such as an aircraft body, to reduce its drag, or resistance to motion through a stream of air. A moving body causes the air to flow around it in definite patterns, the components of which are called streamlines.
Why does streamlining reduce drag?
Streamlining doesn’t reduce friction, it reduces drag. In air, this is often called air resistance. Streamlining reduces air resistance because it reduces the surface area of the moving object that is put under a large force by the air.
Can you give an example of a time you streamline a process?
For example, you can streamline the work of invoicing clients by ensuring the steps in the process are consistent and repeatable, regardless of who is creating and distributing invoices.
What’s the advantage of streamlined body?
A: Streamlining your body reduces the friction of movement to a minimum thus decreasing overall drag. For fishes having a streamlined body that is smooth helps save energy it would otherwise have to expend swimming.
What are the advantages and disadvantages of frictional force?
Advantages of friction:
- Friction enables us to walk freely.
- It helps to support ladder against wall.
- It becomes possible to transfer one form of energy to another.
- Objects can be piled up without slipping.
- Breaks of vehicles work due to friction.
- It always resists the motion, so extra energy is required to overcome it.
Do birds have streamlined body?
Birds have a streamlined body to make their flight easier through air. Snakes have streamlined body to help them move forward.
How does the streamlined body help the fish?
Fish possess a streamlined body which helps them to swim in water. Fish swim with the help of their fins. Streamlined body helps in orientation of the fish movement in a particular path. The bodies of fish are the streamlined bodies because they have to move in fluids.
What is the importance of fins in fish?
Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling.
What are the advantages of streamlining of vehicles?
Streamline For Automobile Efficiency. A streamlined object will cut through the air with less resistance, just like a sharp knife cuts through materials better than a dull one. Streamlining means less aerodynamic drag and therefore less fuel is needed to propel a car forward.
What animals are streamlined?
Many animals that move through water are streamlined, including different kinds of fish, whales, stingrays, eels, and more. Marine animals are not the only ones with streamlined bodies, weasels are one example of a land dwelling animal with a streamlined body. Most types of birds will also have streamlined bodies.

Which animal has a streamlined body paddle like feet and wing shaped flippers?
Penguin wings are paddle-like flippers used for swimming. The motion of the flippers resembles the wing movements of flying birds, giving penguins the appearance of flying through water.
Why do aquatic animals have streamlined body?
Hint: Streamlined body provides a smooth surface to the animals living in the water. It helps them by making their movement easy. Complete answer: A streamlined body provides a smooth surface to the aquatic animal’s body which reduces resistance in the water by reducing friction and makes movement easy.
Why a fish does not survive outside water?
Answer. A fish can only respire through dissolved oxygen in water. When it is taken out of the water,it is exposed to oxygen which is not in dissolved form. The fish unable ro take in direct oxygen cannot survive.
Why do birds have streamlined body shape?
Eldon Greij describes how birds’ streamlined teardrop shape enables them to fly. The bodies of all flying birds are shaped like teardrops. The streamlining is achieved by specially arranged feathers that reduce the friction that would otherwise act as a drag against the forward-moving body.
Which aquatic animal has no streamlined shape?
Octopus
Which aquatic animals does not have gills?
The two aquatic animals which have no gills are dolphins and whales. These animals must come to the surface in order to breathe as they cannot breathe underwater without gills.
Who has streamlined body?
Complete answer: Birds have a streamlined body to make their flight easier through the air. Snakes have a streamlined body to assist them move forward. Some other animals, such as sharks and dolphins, are streamlined so that they have less resistance when swimming in water.
Do penguins have streamlined body?
Penguins have strong wings and strong pectoral muscles to power them. Their bodies are streamlined as if for flight, so they still cut cleanly through the water. But water is much thicker than air, so their wings are shorter and stiffer than a normal bird’s wings.
Why can an eagle fly and penguin can t?
Unlike the wings of other birds, penguins’ wings are more like flippers that make them particularly suited for life in the water. In fact, penguins are so suited for an aquatic life that their agile swimming looks quite similar to abird flying through the air.
Do penguins get all their food from water?
Penguins all hunt for food in the same way. They can either catch it out of the water, or scrape the smaller food, like krill, off of the underside of the ice. Penguins usually eat krill, squid and fish. There are three main ways that penguins can feed their young.
Do penguins have pink poop?
Penguin poop is pink because penguins eat krill and krill are pinkish. But krill themselves are pink because they eat phytoplankton: tiny marine algae. Ultimately, the pink colouration comes from certain pigments called carotenoids.
Is it likely that a polar bear would ever eat a penguin?
No. Polar bears live in the northern Hemisphere, and penguins live in the southern Hemisphere.
