Precise general statement of flat morphisms being "equidimensional"

$\mathfrak a$-adic Completion of a Ring is Flat

Non-flatness of $k[t]$ as a $k[t^2,t^3]$-module

When does intersection commute with tensor product

Injective module but not flat module?

Is the tensor product over $B$ of two flat $A$-modules flat over $A$?

Is it true that a flat module is torsion-free over an arbitrary ring? Does the reverse implication hold for finitely generated modules?

Flat algebra over a Dedekind domain

Does the fibres being equal dimensional imply flatness?

My proof of $I \otimes N \cong IN$ is clearly wrong, but where have I gone wrong?
