The discussion centers on the feasibility of designing a tube that can completely resist fluid flow, with specific references to the ferrofluidic seal and the Tesla valve. The Tesla valve, noted for its lack of moving parts, exhibits high resistance to backflow but does not entirely eliminate it. The conversation raises questions about the necessary inlet pressure for such designs and the definitions of what constitutes a tube in this context.

Closest device i can imagine is the ferrofluidic seal.ramadhankd said:Hello everyone, I want to ask something. Can we design a tube that can completely resist the flow of a fluid? Maybe using either viscosity or surface tension approach? Thanks
