The Venturi effect is a principle in fluid dynamics that occurs when a fluid flows through a constricted section of a pipe, resulting in a reduction in fluid pressure and an increase in fluid velocity. This phenomenon is named after the Italian physicist Giovanni Battista Venturi, who first described it in 1797. Principle Of Venturi Effect The Venturi effect can be explained through the principles of conservation of energy and the continuity equation. According to the conservation of energy, the total energy of a flowing fluid must remain constant. This total energy includes the fluid’s kinetic energy, potential energy, and internal energy (pressure). When a fluid enters a narrow section of a pipe, its velocity must increase to satisfy the Read more
