Bernoulli Theorem Demonstration Module
Product Code : EL-FMLE-10649
QUICK ANSWER: The Bernoulli Theorem Demonstration Module is used to demonstrate and verify Bernoulli’s Theorem by observing static pressure differences along a transparent Venturi-section conduit shaped as a truncated cone, fitted with seven pressure taps that simultaneously measure the static pressure at each section and connected to an eight-tube manometer board. The conduit’s ends are removable so it can be reversed to give either a convergent or divergent flow path, while a probe (Pitot’s tube) traverses the conduit to measure the dynamic pressure at each section, and a flow control valve regulates the flow rate and pressure for comparing the two orientations. It is designed to sit on a Hydraulics bench top with adjustable legs for leveling and a female coupling for direct connection to the bench supply, directing outlet flow via a flexible hose to the volumetric measuring tank.
The Advanced Bernoulli’s Theorem Demonstration module is mainly composed of a circular section conduit with shape of at truncated cone, transparent and with seven pressure taps to measure, simultaneously, the static pressure of each section; all the pressure taps are connected to a manometer with a water collector (water might be pressurized). The ends of the conduits are removable, enabling to be placed in either convergent or divergent form with respect to the stream direction, and there is also a probe (Pitot’s tube) moving along the conduit or measuring the height in every section (dynamic pressure). Adjusting the control valve located at the end of the module can modify the flow rate and the pressure in the module, and a flexible hose attached to the outlet pipe is directed to the volumetric measuring tank.
For the operation, the module is placed on the Hydraulics bench top and it has adjustable legs for leveling. The inlet pipe ends in a female coupling, which may be directly connected to the bench supply.
