SUMMARY
The discussion centers on the conditions necessary for describing liquid speed using potential flow, specifically emphasizing that the fluid must be incompressible, leading to the equations div(v)=0 and Laplace(fi)=0. Additionally, the velocity field must be conservative, which is contingent upon the fluid being non-viscous. The conversation highlights that general liquid flow is not conservative due to the presence of whirlpools, where the rotor of v is non-zero. The participants seek to understand the physical conditions that determine whether a flow can be classified as conservative.
