So now in this case we are given a pipe basically.
00:03
So the pipe is standing in the vertical direction and there is a water which is flowing in the upper direction.
00:09
So here in the pipe, if we do some assumptions, for example, here if we assume that this is a point which is point one and this is a point which is point, let's say two.
00:27
I'm calling this point as point 2 and this point as point 1.
00:33
Point 1 .2.
00:34
So here i'm assuming the area of course section to be a2 and speed at the point 2 i'm assuming to be b2.
00:43
Here i'm assuming the area to be a1 and speed to be v1.
00:47
Now we know that a1 is equal to a2 which is given to us and we know from the equation of continuity that a1 into b1 is equal to a2 into v2.
00:58
So a1, a2 are the same.
01:00
So b2 would be equal to b1, which means speed won't change.
01:03
Speed will remain the same.
01:06
So the answer to the first part is speed will not change.
01:09
Speed will remain the same...
