paineenergiaa
Paineenergiaa, literally "pressure energy" in Finnish, is a concept used in fluid mechanics to describe the energy associated with the pressure of a fluid. It can be understood in two common ways: as energy per unit volume equal to the pressure p (measured in joules per cubic meter), and as energy per unit weight equal to p/γ, where γ is the fluid’s specific weight (γ = ρg).
In the framework of Bernoulli’s equation, paineenergiaa appears as the pressure term p/γ, one component of the
The concept is particularly useful in hydraulic engineering and piping design. For example, higher pressure in
In practice, engineers distinguish between energy density (p, in J/m^3) and head representations such as pressure
