Bernoulli: p/(ρg) + V²/(2g) + z = constant. Valid for: steady flow, incompressible, inviscid (ideal), irrotational flow along a streamline. The three terms are pressure head, velocity head, and elevation head. Total head (energy per unit weight) is constant. Bernoulli is basis for Pitot tube, Venturimeter, orifice meter.
