Description: All the pressure taps are connected to a manometer with a water collector. The ends of the conduits are removable, enabling to be placed in either convergent or divergent form with respect to the stream direction. 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. A flexible hose attached to the outlet pipe is directed to the volumetric measuring tank.
1.It is used for experimental analysis to study the on-way change law of the total head of the pipe flow and the head of the piezometric pipe and the conversion relationship between potential energy, pressure energy, kinetic energy and loss energy.
2.Quantitative measurement experiments - verification of Bernoulli's equation, and analysis of the applicability of the energy equation.
3.Qualitative analysis experiment - Demonstrate the total water head line and piezometric tube water head line directly displayed by the pressure gauge, the dynamic pressure distribution on the uniform flow and the non-uniform flow section, and the on-way energy conversion law.
4.The influence of variable water level on the vacuum degree of the throat.
5.Verify the Darcy-Weisbach formula for the equal Re number, and verify the local head loss formula experiment.
6.Shows the relationship between the mean velocity of the section and the point velocity.
7.Application mechanism and practice of Venturi flowmeter.
8.Working environment: normal temperature and normal pressure.
9.Relative humidity: ?90%RH.
10.Power supply: AC220V/50Hz.
11.Dimensions:1650×450×1280mm.
