Hi.
00:02
So the question is the pressure of water inside a closed pipe is given.
00:06
So in the given i'll write directly the p1 is equal to 3 into 10 raise to 5.
00:14
I'll say pascal.
00:16
This pressure reduces to 2.
00:18
So p2, this reduces to 2 into 10 raise to 5 pascal.
00:24
On opening the wall, calculate the speed of water flowing through the pipe.
00:28
They have also given this density.
00:30
So, density is, i'll say 10 raise to 3 kg per metric cube.
00:37
And here we need to find the final velocity, that is v2.
00:41
Initially, the velocity v1 will be equal to zero.
00:46
So let's find the value of v2 now...
