Bernoulli's equation - Energy Education
Bernoulli's equation expresses conservation of energy for flowing fluids (specifically incompressible fluids), such as water. It shows the equivalence of the overall energy for a given volume of a fluid as it moves. Bernoulli's equation is an approximation and may sometimes include a term to describe the loss of energy from the system. [1] .
