THIS INTERACTIVE JAVA APPLET WAS DEVELOPED AT UT AUSTIN BY Brian Adams, UNDER THE SUPERVISION OF PROFESSOR. Spyros A. Kinnas, 1997.

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 ).

This Applet represents a system containing two tanks, one is closed and the other is open to the atmosphere, with a manometer installed between them. The closed tank is isolated from the system by a ball valve. The fluid levels in both tanks are at the same height.

The pressure inside of the closed tank can be changed from a minimum of -80 kPa to a maximum of 80 kPa. The Applet will ignore pressures outside of this range. To change the pressure, type the new pressure in the text field and press "enter" on your keyboard. Notice that the pressure gauge displays the change. Predict which way the mercury will move in the manometer and by how much, then click on the red valve to see the results .
