Abstract
The following is continuation of Part I. The emphasis in this part is on inquiring how the frequency and decrement of the oscillation are related to the viscosity and density of the fluid for cups of various shapes and sizes. In particular, estimates are made of the errors that would result from calculations of the viscosity and density from observed values of the frequency and decrement and known experimental uncertainties of the latter. Methods are also described which enable one to perform these calculations explicitly.
Zusammenfassung
Diese Notiz ist eine Fortsetzung des ersten Teiles. Hierin wird insbesondere die Frage behandelt, wie die Frequenz und das Dekrement der Schwingung von der Viskosität und Dichte der Flüssigkeit, bei Verwendung von Bechern verschiedener Gestalt und Grösse, abhängt. Vor allem wurden die Fehler abgeschätzt, die bei der Berechnung der Viskosität und der Dichte aus den beobachteten Frequenz- und Dämpfungswerten auftreten können und wenn letztere mit bekannter experimenteller Ungenauigkeit bestimmt wurde. Weiterhin sind Methoden angegeben, wie diese Berechnung leicht erfüllt werden kann.
