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 ...
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 ...
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 ...
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 ...

El experimento explica los principios fundamentales de la formación de imagen con un algoritmo CT. Un simple objeto de prueba se usa para crear una tomografía de atenuación y una tomografía de tiempo de vuelo seguido con una discusión de las ...
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 ...
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.
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 ...
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
PHYWE presenta la nueva unidad de rayos X: tecnología innovadora, máxima seguridad y comodidad.
