In Bernoulli's equation, which term represents elevation head?

Explanation:
In Bernoulli's equation, energy per unit weight along a streamline is written as the sum of three heads: pressure head, velocity head, and elevation head. The elevation head is the height above a reference level, and it’s represented by the height variable z. It corresponds to gravitational potential energy per unit weight and increases with height. In the common form p/ρg + v^2/(2g) + z = constant, the term that captures elevation head is z. The other terms account for pressure energy (p/ρg) and kinetic energy (v^2/(2g)).
