Imagine a solid rod passing through a cylinder filled with a fluid at certain pressure -
The yellow part inside in the fluid, the cylinder has been made transparent for ease.
To make the fluid not leak, the sealing of the rod and cylinder should be completely sealed...this has been done, but rod cannot be rotated in this situation independent of the cylinder.
If it has to be rotated, there should be a friction lining on the sealing which will allow the rod to rotate yet maintain the sealing; but this way is inefficient, i.e since there's friction, there will be a resistance to the rotation of the rod and the sealing with degrade with time as the rod continues to rotate.
So is there any efficient way known to do the same as above; for example with bearing so as to reduce friction?
