Answers
Bernoulli’s principle states that -
The total mechanical energy of the moving fluid comprising the gravitational potential energy of elevation, the energy associated with the fluid pressure and the kinetic energy of the fluid motion, remains constant.
Bernoulli’s principle can be derived from the principle of conservation of energy.
Relation between Conservation of Energy and Bernoulli’s Equation-
Conservation of energy is applied to the fluid flow to produce Bernoulli’s equation. The net work done is the result of a change in fluid’s kinetic energy and gravitational potential energy. Bernoulli’s equation can be modified depending on the form of energy that is involved. Other forms of energy include the dissipation of thermal energy due to fluid viscosity.
