Fluid Flow Venturi Apparatus ME-8598 P Bernoulli effect P Continuity equation The Venturi apparatus has a channel with varying cross-section to study the relationship between flow speed and pressure. The open design (2D cross section) allows students to see inside and directly measure all needed dimensions. There are four built-in ports to attach pressure sensors to measure the pressure at four places along the stream line simultaneously. Pressure changes caused by both fluid speed and viscosity (drag) can be measured. Designed to work with both air (see photo at right), and water (see below). Spirometer (Measures air flow) P 1 P 2 P 3 P 4 P 2 and P 4 are in Venturi Constriction Quad Pressure Sensor Venturi Apparatus The Venturi Apparatus (above) is shown using a shop vacuum as the air source. A Spirometer (PS-2152) measures air flow and a Quad Pressure Sensor (PS-2164) measures air pressure in four locations. See graph at left. P 2 and P 4 are in the Venturi constrictions, and P 4 is downstream from P 1 . Note: the captured O-ring seal in the cover. The graph (above shows water pressure data at three different flow rates. The flow rate is calculated using Motion Sensor data of the water level in the graduated cylinder. The clear plastic cover can be easily removed so that students can measure the dimensions of the Venturi channel. Venturi Apparatus shown with Quad Pressure Sensor (PS-2164), Motion Sensor (PS-2103A), and the Water Reservoir (ME-8594) Includes Venturi Chamber Tubing (for both air and water) Restriction Clamps (2) Quick Connect Couplers Order Information: Venturi Apparatus .................................................

Fluids Bernoulli Cart Accessory ME-9481 P Bernoulli forces This 5 cm diameter cylinder with precision ball bearings, easily set spinning by pulling a string, provides an excellent demonstration of the Bernoulli Principle. Requires a fan to provide airflow across the rotating cylinder. Compatible with all PASCO Carts. this direction. Cart moves in this direction. Track Front of Cart Using the Super Fan Cart to create wind, the Bernoulli Cart Accessory accelerates down the Dynamics Track. (See pages 26-27 for information on carts and tracks.) Fan Lower Higher Air Air Speed–– Speed— Lower Higher Pressure Pressure Fan Lower Air Speed–– Higher Pressure Top view of the rotating cylinder on the Bernoulli Cart Accessory.

Its unique shape creates a stable toroidal vortex. Pull back the flexible membrane, release and the invisible wave front of air can hit a target 20 feet away! A great demonstration of the energy that can be stored in waves. Rotational Acceleration Tank ME-8957 ME-8957 Rotational Acceleration Tank mounted on ME-8950A Rotating Platform.
