Introduction

0 1 2 -0 9 4 8 6 B

In the Venturi Apparatus, air or water flows through a channel of varying width. As the cross-sectional area changes, volumetric flow rate remains constant, but the velocity and pressure of the fluid vary. With a Quad Pressure Sensor connected to the built-in Pitot tubes, the Venturi Apparatus allows the quantitative study and verification of the Continuity Equation, Bernoulli’s principle, and the Venturi effect.

The model ME-8598 Venturi Apparatus includes the connectors and tubing needed for doing the experiment with either air or water. This manual contains complete experiment instructions, including several options for fluid supply and flow-rate measurement.

I n t r o d u c t i o n

Theory

An incompressible fluid of density

ρ

flows through a pipe of varying diameter (see Figure 1). As the cross-sectional area decreases from A

υ

0

0

(large) to A (small), the speed of the fluid increases from

to

υ

.

The flow rate, R, (volume/time) of the fluid through the tube is related to the speed of the fluid (distance/time) and the cross-sectional area of the pipe. The flow rate must be constant over the length of the pipe. This relationship is known as the Continuity

Equation, and can be expressed as u

As the fluid travels from the wide part of the pipe to the constriction, the speed increases from

Experiment

This experiment can be conducted with either air or water. Appendix B contains equipment lists and instructions specific to each method.

Note: You can use a PASPORT interface (or interfaces) connected to a computer running

DataStudio software or on an Xplorer GLX interface in standalone mode (without a computer).

For instructions on collecting, graphing, and analyzing data, press F1 to open DataStudio on-line help, or see the Xplorer GLX Users’ Guide.

Pre-Setup Measurements

Remove the top plate from the apparatus. Measure the depth of the channel and the widths of the wide and narrow sections. Calculate the largest cross-sectional area (A

L

) and the smallest cross-sectional area (A

S

).

Setup

1.

Connect the Quad Pressure

Sensor to your PASPORT interface (but do not connect tubing to the pressure ports yet). If you are using a computer, start DataStudio.

Quad Pressure Sensor

2.

Calibrate the Quad Pressure

Sensor (see Appendix A).

3.

Connect each of the four pressure tubes extending from the underside of the apparatus to the ports of the Quad Pressure

Sensor as indicated in Figure

2.

Important: Do not allow water to enter the sensor. Ensure that there is no water near the sensor end of the pressure tubes.

To Quad Pressure channels: 1 2 3 4

4.

Place the top plate on the apparatus and secure it with

Fluid flow

Figure 2: Quad Pressure Sensor connected to apparatus eight T-knob screws. Tighten the screws no more than necessary to prevent leaking.

5.

Set up the fluid supply and flow-rate measurement as described in Appendix B.

Procedure

1.

Start fluid flow.

2.

Start data collection on the computer or interface.

3.

Continue data collection while observing the pressure measurements on a graph display. Obtain a few seconds’ worth of good data before stopping data collection and fluid flow.

Analysis

1.

View your data on a graph of pressure versus time.

2.

Select a time interval of about 2 seconds in which all off the pressure measurements are relatively clean (though not necessarily constant or noise-free).

3.

Within this time interval, determine the average of each pressure measurement:

P

1

, P

2

, P

3

(and P

4

if you will do the Further Analysis below).

4.

Over the same 2-second interval, determine the average flow rate, R.

5.

If there were no friction or turbulence in the channel, the pressures in both wide sections (P

1

and P

3

) would be equal; however, you will find that this is not the case. Because the channel is symmetrical about Point 2, you can estimate the pressure lost at Point 2 due to friction and turbulence by assuming that it is half of the pressure lost between Point 1 and Point 3. In other words, if the tube were

®

V e n t u r i A p p a r a t u s 0 1 2 -0 9 4 8 6 B straight, the pressure at Point 2 would be the average of P

1 theoretical pressure:

and P

3

. Calculate this

(eq. 3) P

0

=

P + P

------------------

2

6.

Use the measured flow rate, R, and Equation 1 to calculate the fluid speed in the

wide parts of the tube ( υ

0

), and the speed in the venturi constriction ( υ ).

7.

Use these values of υ

0

and υ

and Equation 2 to calculate the theoretical pressure

(P) in the venturi constriction. Compare this to the actual pressure measured by the sensor (P

2

).

Further Analysis

Repeat the analysis above for Points 2, 3, and 4.

Clean-up

1.

Allow the water reservoir to run empty. Tilt the apparatus to empty water from it.

2.

With the apparatus empty of water, disconnect the pressure tubes from the sensor.

(Leave the tubes connected to the underside of the apparatus.)

3.

Remove the top plate from the apparatus. Allow the apparatus and tubing to dry completely.

Storage

Store the apparatus with the top plate loose to avoid permanently deforming the seal.

Appendix A: Quad Pressure Calibration

The purpose of this calibration is to fine-tune all four pressure measurements so they read the same when exposed to the atmosphere. This will allow the small pressure differences that occur in the apparatus to be measured more accurately.

Conduct this procedure with all four pressure ports exposed to the same pressure.

Appendix B: Fluid Supply and Flow Rate

Measurement Options

You can conduct the experiment using air or water as the fluid. In either case, you have a range of options for how to handle the fluid and how to measure the flow rate.

Some of the possibilities are described in this appendix.

In many of these setups, a PASPORT sensor is used to measure the flow rate. You can connect this sensor and the Quad Pressure Sensor to a single multi-port interface

(such as the Xplorer GLX or PowerLink) or use two single-port interfaces connected to your computer. If you have only one single-port interface, measure the flow rate and pressures in two separate data runs.

Air

Air Supply Method 1: Shop Vacuum

Included Parts Required

Rubber stopper with hole

Other Parts Required

Shop vacuum or similar air supply

This method will typically produce a flow rate of 2 L/s or more.

Use a shop vacuum cleaner (Shop-Vac

®

brand or similar) as an air supply. Almost any model will work, but one that has a hose connection for blowing air out may be preferable since it can push (as well as suck) air through the apparatus. Air supplies designed for airtracks will work, but they may produce less air flow than a shop vacuum.

The Venturi Apparatus includes two rubber stoppers with holes. Use one of them to connect the hose of the shop vacuum to the inflow port of the apparatus (see Figure

5). Connect the hose to the air-blowing port of the shop vacuum.

To measure airflow, connect a spirometer sensor as described on page 9.

Note: Observe the correct direction of airflow through the apparatus indicated in Figure 5. If you will be using the shop vacuum to suck air through the apparatus, connect it to the outflow port, and connect the spirometer to the inflow port.

Air Supply Method 2: Balloon

Included Parts Required

Rubber stopper with hole

Short piece of fluid tubing (about 10 cm)

Restriction Clamp

Other Parts Required

Rubber balloon

Balloon pump (available at party supply stores)

This method will produce a flow rate of about 0.5 L/s.

Stretch the mouth of the balloon around the rubber stopper. Insert the piece of fluid tubing into the hole in the stopper. Place the restriction clamp on the tubing. Use a pump to inflate the balloon through the tubing. Close the clamp to hold the air in the balloon. Remove the pump, and connect the tubing to the inflow port of the apparatus

(see Figure 7). Open the clamp to start the flow of air.

To measure airflow, connect a spirometer sensor as described below.

Note: Using a pump to inflate the balloon ensures that the air will be relatively dry. A balloon inflated by mouth will introduce moisture into the apparatus.

other end of the spirometer tubing (see Figure 5 or 7). Assemble the mouthpiece and

spirometer handle, and connect the spirometer to your PASPORT interface.

The spirometer automatically calibrates itself every time you start data collection.

During the first few seconds of data collection, it must remain still and away from air currents. A red WAIT light and green READY light illuminate to indicate when the sensor is calibrating and when it is ready to measure air flow. Start data collection (by pressing or clicking the Start button) with the air supply off, and wait until the spirom-

eter is ready before turning the air supply on.

For more information on the spirometer, see the instructions included with it (PASCO instruction sheet 012-08856).

Set up the apparatus with at least 1.5 m of vertical drop from the top surface of the water reservoir to the bottom of the drain tube. Elevate the reservoir above your lab bench and put the catch basin on the floor (see Figure 8).

Cut the water tubing into two pieces of suitable length. Connect one piece of tubing to the outflow port of the apparatus and run it over the side of the lab bench into the catch basin.

Secure the tubing so water will not spill onto the floor. Place both hose clamps on the outflow tubing. Close one of the clams partially to regulate the flow rate. Close the other clamp completely; you will open and close this clamp to start and stop water flow.

Run the other piece of tubing from the reservoir to the inflow port of the apparatus. Connect the tubing to the bottom hose fitting of the model ME-8594 Water Reservoir, or (if you are using a container without a hose fitting) set up the tubing as a siphon.

Open the clamp to let some water through the apparatus; then close it. Initially, there will be air in the apparatus; tilt it so that the air moves to the outflow port. Let some more water through to flush out the air. Repeat this process until all air has been removed from the apparatus and inflow tubing. Do not let the reservoir run empty, or new bubbles will enter. Close the clamp. Refill the reservoir.

1.

Set the switch on the motion sensor to the near-range setting.

2.

Clamp the motion sensor above the reservoir. Position the sensor very close to the top of the reservoir so it will measure the distance to the surface of the water

(see Figure 9). The water surface should be at least 15 cm from the sensor.

3.

Test the setup: Start data collection and start the water flow. Look at velocity versus time data on a graph display. Adjust the position and angle of the sensor so that you get good velocity data as the water drains. (It is not necessary to get good data over the entire range of water level, since you will only need about 2 seconds’ worth of data.) Stop water flow and refill the reservoir. Delete your test data.

4.

Create a flow-rate calculation: In the DataStudio Calculator window (or GLX

Calculator screen) enter the following definition:

R = v * A

Define the variable v as the velocity measurement. Define A as a constant equal to the horizontal cross-sectional area of the inside of the reservoir. Measure the area in units of m

If are using the model ME-8594 Water Reservoir, or similar container, a separate graduated cylinder is not necessary; simply note the initial and final volumes in the reservoir.

1.

Start with the catch basin empty.

2.

Start the stopwatch and open the clamp to start water flow.

3.

After a measurable amount of water has flowed through, stop the stopwatch and close the clamp.

4.

Measure the volume of water that flowed out of (or into) the apparatus.

5.

Calculate the average flow rate:

⁄ Δ t where

Δ

V is the volume of water and

Δ

t is the elapsed time.

Typically the flow rate varies with the level of water in the reservoir. To keep the flow rate close to constant, make the pressure measurements with the water level approximately the same as it was for the flow rate measurement.
