Venturi Tube and Qualitative Verification of Bernouilli's Equation
Purpose:To demonstrate operation of a venturi tube and to verify variation of gas velocity with area of tube.
Procedure:Connect the hose to the compressed air source and show different pressures in flow tube by flowing air through system and noting pressure relationships by the level of colored liquid in the tubes.
Hints:We have an alternative setup with only 3 tubes available. It might be a little bit trying for the room 203 but the advantage is that the flow velocity could be controlled with the pump.
Note: the large cros section pipes after the narrowing almost never show the same level as the first large pipe most likely due to the formation of the turbulence (continuity equation does not hold for turbulent flow)
