WebBernoulli’s equation for static fluids First consider the very simple situation where the fluid is static—that is, v1 =v2 = 0. v 1 = v 2 = 0. Bernoulli’s equation in that case is p1 +ρgh1 = p2 +ρgh2. p 1 + ρ g h 1 = p 2 + ρ g … Web14 nov. 2024 · It depends on the energies you are considering. You're right in the "introductory mechanics" sense, energy is conserved when Δ E = Δ K + Δ U = 0 for a system. However, in this case the work is being done by the force (s) associated with the pressure. So one can include this in a change in total "energy" of the system.
