Sciencey odd question just occured in my daily musings...

[GQuigley67]

now they reckon that nothing is in actual fact a solid, it is just made up of densely packed atoms which makes it seem like it is a solid but in actual fact things can pass through it like other atoms.

Most scientific "Facts" are not actual facts, they are theories, as we evolve we learn more and previous "facts" no longer become facts as they have been proven wrong. Most theories contradict each other aswell so they can not all be laws of physics.

This is a sketch of the hydraulic gradient rig as I remember it! The difference in head seen at each vertical is caused by the friction loss due to flow in the pipe. This rig demonstrates it in a really practical way .. of course there are many formulae and methods to calculate theoretical friction losses in pipework systems but seeing is believing!!

interesting stuff, so if the istern was 10m high ie 1bar pressure, regardless of the length of pipe water would come out, just that te pressure will be minmal once the friction losses have decreased with the reduction in velocity?

so at some point the final pipe would show same pressure
