Work-Energy 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:
The purpose of this applet is to determine the power needed in the pump for the
water-jet to pass over the wall. All calculations used in this applet are based
on the work-energy equation.
Assumptions:
- The velocity at the surface of the water tank is negligible.
- The distribution of velocity in the pipe for a given cross section is uniform.
Using the Applet:
- Change the water level in the tank, the angle of the pipe, and the height
of the wall by dragging the yellow mouse handles.
- Change the parameters of the problem more accurately by entering the values
in the textfields. The range of each parameter is:
- Pump's Power: 0 - 10,000 kW
- Tank's Water Level: 0 - 10 m
- Wall Height: 5 - 15 m
- Exit Diameter of the Pipe: 5 - 10 cm
- Pipe Angle: 0 - 90 degrees
A Couple of Details:
- The height of the water in the tank and the height of the wall
are the heights above the datum line.
- With the exception of the pump (which was given an arbitrary size) and
the exit diameter (which would be too small to see anyway),
the applet is drawn to scale.
- For the sake of doing your own calculations, the wall's width is 80 cm, and
the diameter of the pipe at the tank is 83 cm.
