実験 出口のストローの長さの違いでどうなるか？

ძალიან საინტერესო ექსპერიმანტია, რომლის შედეგი ასე აიხსნება თურმე:

いつも詳細に説明していただき、ありがとうございます。

მადლობა თქვენ

あれや、 筒の中を通る液体自体が上にある液体を引っ張るから筒の長い方が液体が抜けるのが早いんや。

フォロワーさんが調べてくれました。

おぉ！ これこれ！

てことはデカい人の方がトイレ早いのか

煙でもほぼ同じ効果がある 煙突は長い方が吸い上げる力が上がって火力が増す

My best guess is that the longer straw creates a larger pressurized space which creates a greater sucking effect on the fluid than the shorter straw. Similar to how longer barrel firearms tends to produce higher velocity projectiles.

The length isn’t what’s important. The height of the exit is. There’s a different pressure at different heights. The pressure differential determines speed

La presion de vaciado depende d ela altura de la columna de liquido si cortas la pajita es menor la.presion ergo mayor el tiempo

下に水車を置いたら速度の差が分かりやすくなるかな？

The same reason a long barreled rifle has more power

これマジで小学校の時の知能テストで出ていまだに答えが謎だった

That doesn’t make sense. There more friction loss on the longer straw

@ArthurHovsepian @FieldMarshalPSO

左の方がストノー内部の抵抗が少ないから早いかと思った ストロー内部の落下エネルギーが後ろの液体を引っ張る効果があるんですね サイフォンの原理と同じ効果かな

Well that was unexpected.

I don't believe that experiment.

Inverse ciminery effect.

@grok The result would be different with something not water-based or no?

So this is why it sounds like I piss lake a race horse.

难道是剪的那一下的力量把吸管挤扁了？

Good explanation for why full length exhaust headers make more power over manifolds

Pressure from distance from the top of the liquid

Do it again and pinch the same distance from the bottom of the container

now bend the straws so they run sideways

it can maintain laminar flow longer and gain more speed through the long straw

ポンプとかで使う力学

おお！銃のバレルの長さの効果と同じかな

Curioso.

suction pressure.. the liquid falling in the straw will get a mechanical pull on the liquid through suction.

Deney biraz hatalı çünkü bardaktaki sıvı bardak altından ilk boşalmıyor pipet ucunda başlıyor

Sucede lo mismo con el tiro de una chimenea

that's interesting
