The static outlet pressure … WebFeb 8, 2024 · When gravity is on, the pressures have confused me a lot. To be specific, I understand the static pressure is the (gauge) thermodynamic pressure, as a property. And I also grasp the idea of using a modified pressure in N-S equations. But I am confued about the definitions of absolute pressure and total pressure.
