I am with a simple experiment today!`
Things we need-:
Beaker with water (I am taking 200ml of water)
Beaker with no water
Put the funnel on the mouth of beaker with leaving no space on sides. Now start putting water in the beaker through funnel
It taken 9.89 seconds to move 200ml of water
But now put it like this
In this case it taken 6.86 seconds to move 200ml of water.
Now let’s see how it happens
There is only one hole for both things which are air going out and water coming in. Air is coming out then Water is going in from same hole.
But in Case 2
Water goes inside the beaker first (through funnel) then water throws Air out, the air comes out from sides.
It caused difference of 30% of time (approximately)
