A law of fluid mechanics which explains relationship between the velocity, density, and pressure of a fluid. It states that: P + 1/2 pv2 = constant (P is the pressure, p is the density of the fluid and v is the velocity). Without addition of energy to the system, increase in velocity is accompanied by a decrease in density and/or pressure.

BERNOULLI'S LAW: "Bernoulli's law is directly associated with the principle of conservation of energy. "
