The equation expressing → Bernoulli’s theorem: P + (1/2)ρV² + ρgz = constant, where P is the fluid → pressure, V is → velocity, ρ is → density,
g is the acceleration due to → gravity, and z is the vertical reference → level. The theree terms are called → static pressure, → dynamic pressure, and
→ hydrostatic pressure, respectively. The Bernoulli equation states that the total pressure along a → streamline is → constant.
