Hi, in this question we have to use bernoulli's equation that is p1 by rho g plus v1 square by 2g plus z1 is equal to p2 divided by rho g plus v2 square divided by 2g plus z2 plus loss.
00:15
So, here we have so on substituting we have 0 plus 0 plus 60 is equal to 0 plus v2 square by 2g plus 0 plus hf plus h2.
00:25
So, here we have 60 is equal to v2 square divided by 2g plus hf plus h2 where hf is the head loss and h2 is the head loss.
00:35
Then we have the value of hf is given by it is k into v square divided by 2g or this is the value of h2 which is equal to 80 into v square divided by 2g and we have the value of hf is given by e by d.
00:50
So, here e by d into l into v square divided by d into 2g.
00:56
So, on substituting we have 0 .005 into 500 into v square divided by d square into 2g.
01:04
Now we have on substituting in the bernoulli's equation we have 60 is equal to v square by 2g into 1 plus 25 by d square plus 80.
01:15
So, from this we have the value of discharge is given by a into v that is equal to v into 5 by 4 into d square.
01:24
So, from this we have v is unknown.
01:27
So, here we have this is 0 .3...
