Bernoulli’s Theorem Demonstration Apparatus FM 03
Bernoulli’s Theorem Demonstration Apparatus FM 03
Sci-tech Bernoulli’s Theorem Demonstration Apparatus Model FM 03 is a bench top unit and has been designed to demonstrate the Bernoulli’s Theorem. The apparatus consists of a transparent venturi tube. Wall pressure tapings are provided along the converging and diverging portions of the venturi to measure the static pressure distribution. Pitot tubes are provided to along the centre line of the venturi. Static pressures are measured using multi-tube manometer having a manifold with an air bleed valve. Manometer can be pressurized by a hand pump. The characteristics of the flow in both convergent and divergent portions of the venturi can be studied. This apparatus can also be used to conduct laboratory experiments to (a) demonstrate the continuity equation and (b) determine the co-efficient of discharge of venturi as a flow measurement device. Water is supplied by a hose connection at the inlet and controlled by a valve at the outlet of the venturi.

Item Description
Sci-tech Bernoulli’s Theorem Demonstration Apparatus Model FM 03 is an important experimental set-up for any Fluid Mechanics and Hydraulics Laboratory of an educational institutions.
The Bernoulli’s Theorem states that the sum of pressure head, velocity head and the potential head is constant along a streamline for a steady, in viscid and incompressible flow of fluid. The Sci-tech Bernoulli’s Theorem Demonstration Apparatus Model FM 03 is a bench top unit and has been designed to demonstrate the Bernoulli’s Theorem. The apparatus consists of a transparent venturi tube. Wall pressure tapings are provided along the converging and diverging portions of the venturi to measure the static pressure distribution. Pitot tubes are provided to along the centre line of the venturi. Static pressures are measured using multi-tube manometer having a manifold with an air bleed valve. Manometer can be pressurized by a hand pump. The characteristics of the flow in both convergent and divergent portions of the venturi can be studied. This apparatus can also be used to conduct laboratory experiments to (a) demonstrate the continuity equation and (b) determine the co-efficient of discharge of venturi as a flow measurement device. Water is supplied by a hose connection at the inlet and controlled by a valve at the outlet of the venturi. The complete unit is manufactured from corrosion resistant materials. The FM 100F Hydraulic Bench or any other standard hydraulic bench models can be used to supply water.
