Streamlining is a design that offers the least resistance to the flow of liquid. Friction is minimum for the streamlined shapes, which is generally rounded in the front and narrow at the back. ... The bodies of rockets, cars, aeroplanes are streamlined to reduce the friction with the air.

What is streamline in friction?

Streamlining is the process by which the designs of moving body are made in such a way that the resistance or friction due to fluid is reduced. When objects move, the air around them generates a type of friction called air resistance, or drag, that slows them down.

What is streamlining short answer?

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.

How does streamlining reduce friction?

STREAMLINING. When objects move, the air around them generates a type of friction called air resistance, or drag, that slows them down. ... designed with curved and sloping surfaces to cut through the air and reduce drag. This helps them to move faster and use less fuel.

What is streamlining give two examples?

A special shape of the bodies which reduces the fluid friction is called as the streamlined shape. Example: Aquatic animals like fish, crocodile and sharks and the vehicles like cars, flights, ships ect. Streamlined shapes help reduce the amount of air drag when an object is moving.

What is streamlining and example?

Streamline is something that has a shape that provides little resistance to air or fluid flow. An example of streamline is a slick, smooth aircraft. ... A line that is parallel to the direction of flow of a fluid at a given instant.

How a streamline is defined?

A streamline is a path traced out by a massless particle as it moves with the flow. It is easiest to visualize a streamline if we move along with the body (as opposed to moving with the flow). ... Since the streamline is traced out by a moving particle, at every point along the path the velocity is tangent to the path.

Why is streamline important?

Why Streamlining Processes is Important

Streamlined processes generally mean fewer errors and delays. Operational efficiency and quality of work can greatly improve as well. ... Ability to quantify processes to evaluate efficiency and identify potential improvement areas. Lower expenses with improved efficiency.

What is streamlining how is it useful?

Streamlining is a design that offers the least resistance to the flow of liquid. Friction is minimum for the streamlined shapes, which is generally rounded in the front and narrow at the back. ... Ships have a streamlined shape, which helps to reduce friction with the water.

What is streamlining in biology?

Genomic streamlining is a theory in evolutionary biology and microbial ecology that suggests that there is a reproductive benefit to prokaryotes having a smaller genome size with less non-coding DNA and fewer non-essential genes.

What is streamlined flow?

A streamline flow or laminar flow is defined as one in which there are no turbulent velocity fluctuations. ... The definition of a streamline is such that at one instant in time streamlines cannot cross; if one streamline forms a closed curve, this represents a boundary across which fluid particles cannot pass.

What is streamlining in science class 6?

A streamlined body is a shape that lowers the friction drag between a fluid, like air and water, and an object moving through that fluid. Drag is a force that slows down motion; friction drag is a special kind of drag.

What is streamlined shape Class 8?

A body shape which offers very little resistance to the flow of air or water around it is called streamlined shape. A streamlined shape is like thin wedge or triangular objects lying on its base and sloping upwards gradually.

What is a streamlined object?

Answer:Streamlined objects would include objects that are designed to travel quickly and create a minimum of friction against either air or water. Some objects that are streamlined include trains, airplanes, space shuttles, rockets, boats, submarines, racing cars, racing boats, and even televisions.

What is streamlined shape explain and give two examples?

Answer: A special shape of the bodies which reduces the fluid friction is called as the streamlined shape. Example: Aquatic animals like fish, crocodile and sharks and the vehicles like cars, flights, ships ect. Streamlined shapes help reduce the amount of air drag when an object is moving.

What is streamline shape?

A streamlined body is a shape that lowers the friction drag between a fluid, like air and water, and an object moving through that fluid. ... It offers a minimum resistance to air and water by its particular type of body shape .

What is the definition of a streamline what do streamlines indicate?

A streamline is a curve that is everywhere tangent to the instantaneous local velocity vector. The streamlines can indicate the direction of flow of the fluid instantaneously in a flow field.

What are the two methods of reducing friction?

There are various ways to reduce friction:

• By using lubricants: friction increases as the roughness of the surface increases. ...
• Polishing surfaces: It makes the surfaces even and hence reduces friction.
• By using ball bearings: Rotating machines can be mounted on ball bearings.
