A topic that seems to come up in just about every NWGLDE meeting is the presence of a crack (orifice) on the side of a UST, and the amount of the liquid that escapes from this hole. This topic also came up in the recent Technical Panel Meeting organized by Battelle. Our computer program answers this question when the height of the fuel, the size of the crack, and some other variables are varied.
Mathematica published this program and it is now online. We are very pleased and honored by having our program published in Mathematica’s Demonstrations Project and we think a lot of engineers, researchers, and field engineers will use it to obtain the exact amount of leakage for various heights, different “crack sizes”, and various coefficient of discharge. To really see this program in action a user needs to have Mathematica installed or download the Mathematica Player. Mathematica Player and all the demos are free and may be downloaded at anytime.

Note that leakage is a function of height, “h” so above may be applied to both vertical and horizontal tanks.
