1. Do Steps 1 - 6 From Area to Volume Volume of a Cone = 1/3 Π r2 * h
Alpha
Beta
Volume of a Cone = 1/3 Π r2 * h
Consider the trap to be
approximately ½ a cone r r r h
Slide 17
We have to go from an area to a volume
Time for another simplifying assumption
Let’s assume the trap has the basic form of one-half of a cone
We know the volume of a cone = 1/3 (pi) r2 * h
As you did with the area, you can estimate the conical volume from the top of the reservoir to the
fluid contact and subtract the conical volume from the base of the reservoir to the fluid contact
Use the base map to estimate the 2 radii and the 2 heights for Alpha and for Beta
Now you can follow the instructions in the exercise and work parts 1 through 4
Do Alpha ONLY first; if you have time and the desire, go back and do Beta
