Bernaulli’s Equation
This is Bernoulli’s equation for an incompressible fluid, i.e. a fluid that cannot be compressed or expanded, and for which the density is invariable.
First term is the internal energy of unit mass of the air, ½ v² is the kinetic energy of unit mass and gz is the potential energy of unit mass. Thus, Bernoulli’s equation in this form is a statement of the principle of conservation of energy in the absence of heat exchanged and work done.
