There we will be able to address the question, "How does one specify pressure-driven (Poiseuille) problems with a pressureless governing equation?" Source: Internet
The first equation is a pressureless governing equation for the velocity, while the second equation for the pressure is a functional of the velocity and is related to the pressure Poisson equation. Source: Internet
