Question

Why do we need to define potential energy head or gravitational head or any head for that matter? In reference to one of the forms of Bernoulli's theorem.​

Answer 1

Answer:

In fluid dynamics, Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in static pressure or a decrease in the fluid's potential energy. ... This requires that the sum of kinetic energy, potential energy and internal energy remains constant.
