Bernoulli’s principle demonstration unit tends to illustrate Bernoulli’s theory, which describes the relationship between the flow velocity and pressure of the fluid. This is done by measuring the pressures in a venturi nozzle.

  • The demonstration unit is used to study the static pressures and total pressure distribution along with the venturi nozzle.
  • The experimental unit is positioned easily and securely on the work surface of the main hydraulic unit that acts as the supply of water to the unit.
  • The experiment was run based on Bernoulli’s principle states that for an invincible flow, an increase in the speed of the fluid occurs simultaneously with a decrease in pressure or a decrease in fluid potential energy.
  • All pipes are transparent for clear investigation of the experiment for students.
  • The educational unit include venturi and movable pitot tube which is used to measure the total pressure.
  • The Pitot tube and Venturi are in an axial position and the position of measuring can be easily investigated with pitot tube inside the venturi with a clear transparency system.
  • The system includes a manometer with 6 tubes for displaying measuring points of static pressure & one for pitot tube which is used to measure the total pressure.
