Suction and Pressure Fan with Venturi Tube

Students measure pressure with a precision manometer.

• Precision Manometer
• Students Visualize Pressure Differential
• Suction and Pressure Fan
• Venturi Tube Measures Volume Flow
• Multi-Manoscope

In this experiment, the static pressure in a Venturi tube is measured for different cross-sections. The static pressure decreases in the reduced cross-section as the flow speed increases.

The Venturi tube can measure the volume flow using the pressure difference Δp = p2 - p1 between two points with known cross-sections A1 and A2.

Ordering information: This kit includes a suction and pressure fan, Venturi tube with multi-manoscope, precision manometer, small stand base (V-shape), small stand rod (25 cm, 12 mm ø), stand rod (47 cm, 12 mm ø), and a Leybold multi-clamp.
