All things are flowing.

mass flow rate
volume flow rate
If the fluid is compressible, then we use the mass flow rate…
|I =||m||= ρAv = constant||⇒||ρ1A1v1 = ρ2A2v2|
For incompressible fluid flow, we use the volume flow rate…
|φ =||V||= Av = constant||⇒||A1v1 = A2v2|
Notes from The Economist. "A sverdrup (named for the Norwegian oceanographer and meteorologist Harald Sverdrup) the unit in which ocean currents are measured, is one million cubic metres of water per second. The Gulf Stream, the northern part of a circulation system known as the North Atlantic Gyre, reaches 150 sverdrups at its peak. On average, it flows at around 100 Sverdrups.
Bernoulli's equation is based on the law of conservation of energy; the increased kinetic energy of a fluid is offset by a reduction of the "static energy" associated with pressure. The fluid is assumed incompressible and inviscid (that is, the fluid does not generate drag).
Something like this is probably right.
|P1V1||−||P2V2||=||(U2 − U1)||+||(K2 − K1)|
Rearrange and assume the fluid is effectively incompressible (i.e., that it's volume remains constant as it flows from one region to another).
The conclusion is most certainly right
P1 + ρgy1 + ½ρv12 = P2 + ρgy2 + ½ρv22
The third term in this equation is the dynamic pressure (q).
q = ½ρv12
