WebbBernoulli's Equation General Energy Equation. The conservation of energy principle states that energy can be neither created nor destroyed. Simplified Bernoulli Equation. … In most flows of liquids, and of gases at low Mach number, the density of a fluid parcel can be considered to be constant, regardless of pressure variations in the flow. Therefore, the fluid can be considered to be incompressible, and these flows are called incompressible flows. Bernoulli performed his experiments on liquids, so his equation in its original form is valid only for incompressible flow.
