Non-slip condition for inviscid fluids

[mech-eng]

Hi, I would like to ask that whether or not $non-slip condition$ is valid for inviscid fluids. We know that inviscid fluids there is no friciton. If there is no friction in the inner surface of pipe (I do not name its technical name) so it seems that there cannot be the non-slip condition. This confuses me. Would someone like to explain it?

Thank you.

No it is not valid.

If there is no friction, why has to be a non-slip condition, what will create non-slip condition if there is no fricition?

Thank you.

And I have did: number sign non-slip condition number sign but "condition" joined to "slip" in my first post in this thread. what was wrong in using LateX?

Thank you.

There is no "no slip" condition in inviscid flow. Only the no penetration condition exists.
