P1 + ρgh1 + 0.5ρv21 = P2 + ρgh2 + 0.5ρv22
In the derivation of this equation from the theorem of Work-Kinetic Energy, pressures ( P1 and P2) represent are derived from F = PA, forces affected by other portions of fluid upon the fluid in the middle (which is our concern) at 2 different points. So do we consider them the pressure of the fluid itself or the pressure exerted by surroundings on the fluid?
