Rotating UTube Applet
THIS INTERACTIVE JAVA APPLET WAS DEVELOPED AT UT AUSTIN BY Kyle Douglas, UNDER THE SUPERVISION OF PROFESSOR. Spyros A. Kinnas, 1998.
PERMISSION TO LINK TO THIS JAVA APPLET AND TO DOWNLOAD OR TO USE THE RELATED JAVA SOURCE CODE, MUST BE GRANTED BY PROFESSOR Spyros A. Kinnas ( kinnas@mail.utexas.edu ).
Purpose:
This applet shows the change in water level due to rotation of the water in a UTube. Rotation
occurs about a vertical axis through the center of the gray shaft. Equations for this applet
come from the behavior of a fluid under radial acceleration.
Using the Applet:
Note: The Original Water Height refers to the height of the water without rotation.
 Drag the yellow handles to change the Angular Velocity, the Original Water Height, and the axis of rotation.
 Enter values for Angular Velocity, Original Water Height, and the distance from the center
of the tubes to the axis of rotation for more accurate control over the parameters.
