Class#2 Aerodynamic and Hydrodynamic Systems

Word Definition
Aerodynamic- air affects the movement of a solid things


*Japanese bullet trains wii be a perfect example of an aerodynamic object

  Hydrodynamic- something that affects the movement of water around an object


*Torpedos are shaped hydrodynamically to be able to move fast under water


Laminar Flow- when a flow of water is in a straight or close to being straight
example- a deep river without any obstacles underwater has a laminar flow

Turbulent Flow- a flow of water in an irregular way produced by rapids, eddies, or whirlpools
example- a steep river with many obstacles such as rocks has a turbulent flow

Laminar rivers flow smoothly when turbulent rivers flow in somewhat kind of an odd way

Drag- something that concerns with the speed of water(liquid) that resists agianst its flow
Streamlined- an objects is said to be steamlined when an object is made in a shape that helps reduce the resistence of water as much as possible

sharks move smoothly underwater especially that creates a laminar flow

How a type of technology is built to minimize air resistence??0.0

Type of technology built to minimize air resistence are parachutes. They are built in a circular way to minimize air resistence.
