Bernoulli's equation is directly derived from the conservation of which of the following?

  • A.Mass
  • B.Volume
  • C.Momentum
  • D.Energy

Answer: D

Bernoulli's equation is derived from the conservation of energy. It is the energy equation for a flowing fluid along a streamline, in which pressure energy, kinetic energy and potential energy add up to a constant. The conservation of mass leads to the continuity equation and the conservation of momentum to the momentum equation, so the answer is energy.
