The reason for this being slower than expected is the water has been colored blue which made it sad and when its sad it takes a bit more motivation from gravity to get it out
I took the over because i've been in college and know that funnels never empty as fast as you expect them to š
Friction/attraction to plastic walls as well as turbulence can account for the difference in time.
I was like "i don't feel like doing that calculus...oh you did do it? I'll take the over."
Buddy I just use my imagination and think how long it would take š
What i learnt:2Ć4 The test:
His reasoning āadvanced mathematicsā My reasoning ābecause of its shape it will take approximately longer than he saidā
As an engineering student i took the over initally, after his explanation of how the base was calculated i knew my choice was right because 4.5 was the best case scenario when not accounting for, fluid drag, friction with the walls, turbulance. And the best case scenario never happens, much less a better than perfect scenario lmao
Over: No matter how good your math is, thereās always one random variable that going to slow everything down.
bro just violated the lakers for no reason
I won that bet handedly. PS: Your equations didn't account for turbulence. If the liquid was spinning before removing the cork, it would have minimized the turbulence, and 4.5 seconds might have been dead on.
For those that are wondering yes you can refill the top of it before the bottom part drains and if you keep doing that enough you'll never get the funnel to be empty. PS they do this with electricity and it's called a capacitor.
That Lakers shot was wild š
Thatās actually cool cause whilst Bernoulliās equation is ādecentā at modelling fluids it doesnāt take into account viscosity like the navier stokes equation. However stokes doesnāt take into account the attraction between the water and the funnel, but I think for this purpose itāll be negligible.
As soon as you said you were using exit velocity I took the over. I'm no mathlete but I feel very strongly that exit velocity should fall as the water pressure goes down
Pov: viscosity entered the chat
I took over bc if itās 4.5 in perfect conditions, anything imperfect will make it longer
I like this science version of your channel.
The only flaw that gave me the over call was its not perfect flow. If you did this with a variable pressure over the top of the funnel that goes up as water flows out, you'd get exactly your calculated 4.5 secs.
