Hello, as we know that as per knowledge equation, p1 by gamma plus v1 square by 2g plus z1 must be called to p2 by gamma plus v2 square by 2g plus z2.
00:15
This is as per knowledge equation.
00:18
So the thickness of the foil is very less.
00:21
So this z1 and z2 can be assumed to be same.
00:24
So both of them cancels out.
00:26
Now we are given that velocity, if this is being, below the blade and this is side of the blade.
00:43
Alright, so the velocity of both the allocation is given to us.
00:47
The pressure difference is required.
00:49
So this pressure difference could be p1 minus p2 by gamma is equal to v2 square by 2g minus v1 square by.
01:03
So velocity downward was, how much? 200 meters per second, right? and velocity upward was 240 meter per second.
01:14
240 square minus 200 square divided by 2 into 9 .81 multiplied by gamma.
01:21
Gamma is what? rho into g, row is 1 .29 into g...
