This video explores Bernoulli's Theorem, highlighting its basis on the conservation of mechanical energy in fluids under specific conditions like streamline flow and the absence of friction or external agents. It offers a detailed derivation of the theorem and illustrates how to calculate mechanical energy in a test volume by considering kinetic, gravitational potential, and pressure potential energies. Various applications and constraints of Bernoulli's Theorem, including comparisons with the continuity theorem, are also discussed.
