Mechanics of flow

Principle

The ultrasonic Doppler effect is used for studying the laws of steadily and laminarly flowing liquids in a tube circuit, which form the basis of numerous technical applications. The experiment focuses particularly on the relationship between the flow velocity and the cross-sectional ...

Flow Measurement

Principle

The aim of this experiment is to study the relationship between the ultrasonic Doppler effect and the flow velocity or the Doppler angle.

Benefits

• Ideal for teaching the basics of the Doppler effect in fluids

• Experiment setup can be upgraded to perform experiments like ...

Velocity of ultrasound in solid state material



Principle

The velocity of sound in acrylics shall be determined by time of flight reflection technique with an ultrasonic echoscope. The measurements are done by reflection method, on three cylinders of different length. Two measurement series are carried out with ultrasonic probes ...

Ultrasonic echography (A-Scan)



Principle

An ultrasonic wave transmitted in a sample will be reflected at discontinuities (defects, cracks). From the relationship between the time of flight of the reflected wave and the sound velocity, the distance between ultrasonic transducer and defects (reflector) can be ...

Ultrasonic echography (B-Scan)

Principle

The fundamental principles concerning the generation of ultrasonic B-scan images (brightness representation of the reflection amplitudes) are demonstrated with the aid of a simple test ob-ject. The experiment is executed with an ultrasonic echoscope in the pulse-echo-mode and the ...

Detection of discontinuities

Principle
The experiment demonstrates the application and performance of various non-destructive test methods with the aid of ultrasound. A test object with different types of discontinuities is used to perform various detection methods. First, the test object is scanned in order to determine ...

Ultrasonic computed tomography

Principle

This experiment explains the fundamental principles of image formation with a CT algorithm. A test object is used to create an attenuation tomogram and a time-of-flight tomogram followed by a discussion of the respective differences.

Benefits

• Ideal system for education: ...

Water quality - contamination with heavy metals

Principle

Heavy-metal ions may be carried into surface or ground water from mining fields or via the waste water of galvanic or similar production sites. They block the effect of enzymes so that the processes in the metabolism of the organisms that are controlled by these enzymes may ...

Thermal insulation with measureAPP

A quick loss of heat is sometimes not wanted. What can be done to keep the temperature in a vessel
constant? Students are measuring the cooling of hot water in two different environments.

Thermal insulation with SMARTsense

Heating of water with measureAPP

Principle

How depends the time required to heat up water on the amount of water when a defined heating source is available? The students are heating up various amounts of water with an electric heating coil and measure the time dependence of the ...

Heating of water with SMARTsense

Heating of various liquids with measureAPP

Principle

Do different liquids heat up to the same extent when subject to the same heating? The students are heating 100 g and 100 ml of water and of glycerol with an electric heating coil and measure the temperature in dependence on
