    The Bernoulli equation is an energy equation that can be derived through many methods. In this paper, we derive the Bernoulli equation from the aspect of dynamics based on work-energy principle. We studied the derivation of the Bernoulli equation of the ideal fl uid in steady fl ow. We discussed the physical signifi cance of the equations in diff erent conditions, and then discussed the meaning of dynamic pressure in Bernoulli equation and the relationship between dynamic pressure and static pressure. We also listed out the application of Bernoulli equation in production and in life.
