Fish, seal, sharks, dolphins, and so on, are all streamlined so less energy is wasted swimming through the water. Space rockets, cars (especially racing cars) are streamlined to use less fuel and have less drag holding them back by air friction.

What are the effects of increasing a streamline?

Increasing a streamline results in decreased pressure along the streamline due to conservation of energy. This leads to increased flow velocity and kinetic energy, but the total energy of the fluid remains constant. Additionally, increasing a streamline can also affect the fluid's mass flow rate and streamline density.


What is the stream function for an incompressible flow and how is it used to describe the flow properties?

The stream function for an incompressible flow is a mathematical function that helps describe the flow properties by showing the flow direction and velocity at any point in the flow field. It is used to visualize and analyze the flow patterns and streamline shapes in the flow field.


How do you streamline a non streamlined object?

To streamline a non-streamlined object, you can first identify areas of inefficiency or excess, then simplify the design by removing unnecessary elements or features. Reorganize components to improve flow and minimize resistance, and optimize the shape or structure to reduce drag or friction. Testing and iteratively refining the object's design can also help to streamline its performance.


How do you explain streamline flow?

Streamline flow is a type of fluid flow where the velocity of the fluid at any point remains constant over time. This results in smooth, orderly flow patterns with streamlines that do not cross each other. Streamline flow can occur in idealized conditions with low viscosity and continuous flow.


What is the difference between concave and convex shapes?

Concave shapes curve inward, like a cave, while convex shapes curve outward, like a bump.
