What is streamlining, what does it do and what are some examples of it?

Question

(this is part of my physics homework when studying about falling bodies through fluids)

Answer 1

Efficiency.

First remember that air flow is treated as fluid flow, so air when I talk about air it applies to fluids like water as well.

Aerodynamic means air action and this is how we shape cars so they move faster with less power; another words they are more efficient. Streamlining is the same thing.

A rectangular object will encounter more air resistance, or water resistance for that mater when moving forward. If we were to cut off part of that rectangle and form a smoother shape like a curve we would decrease that resistance. We would also decrease some of the internal volume.

Streamlining is a compromise between efficiency in travel and efficiency in holding volume. The rectangular shape can hold more cargo or passengers, but the streamlined shape will use less fuel to move so it will save on cargo space there. This means that some degree of streamlining is usually the more efficient way to handle a moving object.

Boats are streamlined, curved, and almost smooth on the bottom. The lines that extend into the water help to provide stability and that stability refers to the flow of water as well as the flow of the craft through the water. When water becomes turbulent; unsmooth flow, then it provides more resistance so streamlining also cuts down on turbulence.

The resistance of the water is so much more than the resistance of the air that most boats only have a minimum of air streamlining; it is the part that is in the water that needs more streamlining so it can be more efficient.

When you make an object streamlined or aerodynamic then you are sacrificing internal volume for less resistance and faster speed. Not only that but the minor differences on the hull make a difference as well. American Airlines washes all of its airplanes between flights so they can fly faster, with less resistance, and so save on fuel.

The high tech SR-71 Blackhawk is the fastest plane in the world and it uses super strong tungsten steel to provide a more efficient streamlining. The harder steel won't be distorted by the increased heat and so it makes traveling more efficient. In fact thanks to the design of the aero spike in the intakes it actually goes faster, with less fuel when flying at supersonic speeds. Again this is a case of efficient streamlining in action.

Answer 2

Its designing a vehicle in such a way as to reduce either air or water resistence, so less energy is necessary to move the vehicle. The bullet shape that cars began to display since the 1930s was largely aesthetics, but it was also streamlining. Planes began to show streamlining slightly before that period. The skipjack class of submarines was an early attempt to do the same with naval vessels.

Answer 3

What Is Streamlining

Answer 4

streamlining is reducing friction to an object...or human..lol...examples would be
1.human streamlined=shaving all body hair
2.car streamlined=smooth flowing body lines that appear to put the car in motion..example(ferrari f-40)

Anywhere you dont want to lose energy in form of drag. Naturally it will be for objects moving through fluids, like aircrafts, automobiles, marine vessels, projectile and even some high rise structures are streamlined for lesser pressure forces.

Answer 7

streamlining enables things to pass through other things faster for example the way an f1 car is shaped so it can cut through wind easier. or when diving into a pool of water your arms are out stretched above your head in a pyramid shape so you can split the water for easy entry

Answer 8

Speed skiing: the athletes wear rubber suits with teardrop-shaped fairings on their legs and helmets. They reach speeds of 200 km/h, literally flying on 2-metre skis in the ground effect. Since they are powered solely by gravity the streamlining is very important.
