HOW BIG CAN A RAINDROP GET?
Have you ever wondered how big can a raindrop get?
In this video, we explain the physics behind the size of a raindrop. Starting from the process of its creation to the effect of aerodynamics that plays a vital role in determining the size.
We would also like to take this opportunity to thank every single one of you for supporting us and pushing us to share our curiosity for science.
Thanks for watching, we hope you enjoyed the video. As always don't forget to like share and subscribe.

IS WEATHER PREDICTION HARDER THAN ROCKET SCIENCE? | CHAOS THEORY | BUTTERFLY EFFECT
Просмотров 1,1 тыс.3 года назад
Butterfly effect states that small variations, like the flap of the butterfly in one location on earth can have a large effect like a tornado in another location. In this video, we explain the concept of chaos theory in the the realm of weather prediction. Recently the SpaceX Dragon Crew launch was delayed due to bad weather. This raised the question, how could the team at SpaceX consisting of ...

If only fish could speak.. the stories we would hear. Oh wait! lets back up a bit. We know that sound propagates with different speeds in different media, but can it propagate between media? Can you hear what's happening in the ocean while standing on the shore? In this video we tackle exactly that. We explore the physics of sound propagation between different media and the not at all insignifi...

In this video, we tell you what exactly drag is and how it originates. We also talk about the different types of drag- skin friction drag and pressure drag and how they are different from each other. Pressure drag contributes as the major source of drag in bluff bodies (i.e bodies that are not streamlined). But, drag is not always a bad thing- slipstreaming is a trick used in many sports to red...

In this video, we break down the physics behind swing bowling. We talk about the main cause of swing bowling- asymmetrical boundary layer separation. Conventional swing (in swing and out swing) happens in new shiny balls where the boundary layer is tripped by the seams while reverse swing occurs when the ball is relatively old and the roughness causes asymmetrical boundary layer separation.

    is the friction at the wall of the pipe, actually between this no slip, stagnat layer of fluid and the rest moving fluid? So actually the friction is not with the wall of the pipe, but with the non moving fluid at the wall?

  • @ShonMardani
    @ShonMardani 7 месяцев назад

    Parasite drag is produced by VERTICAL surfaces and Induced drag is created by HORIZONTAL surfaces, for example when the Flaps are at 0 degrees they produce Max Induced drag and Min Parasite drag, at 90 degrees Min Induced and Max Parasite drag and at 45 degrees in the middle of both, for a flap with no thickness. The fact that Lift and drag are both proportional to airspeed squared, means airspeed affects a 2 Dimensional surface, geometrically a Square plane. Wing Vortices are not the cause of Induced Drag but it is just a Visible Effect of it. I have developed a hypothesis to explain physical, atomic and subatomic (gravitational movements, Center of Gravity and Mass), however I need to validate my V & H surfaces theory first. It seems that Winglets reduce Lift and increase Drag, I also believe in turbance Winglets impose additional stress to wings and all other moving parts inside the wings like rods, joints and moving surfaces. Wingtips also decrease the stability and controllability in turbulent air. Simply put another british scam. Please let me know what you think, thanks.
