Need Volume vs. Height Calc Method

[Ralphenstein]

Anybody know a simple calc or online tool I can use to find the exact height from the bottom of a pressure vessel that a certain percentage of volume is contained?

ie. I need to find 80, 85 & 90% fill heights on 90 - 140 cm dia tanks. I am designing some overfill protection devices and could use a good tool to determine these heights.

(heads are semi-circular, and length varies...values will be a function of diameter and fill percentage only)

Thanks in advance for any help, this is my first post!!!

GPSA DATA BOOK Chapter 6.

f(Zc) = (? ? sin (? ) x cos (? ))/Pi

F(Zc) is the partial volume factor. If you put the hieght at 5 Meters on a 10 meter tank you will gwt .5 as F(zc)


? = 2* Atan( H/(sqrt(2*H*D/2)-H^2)) H is partial hieght and D is total diameter.

This is just for the cylinder.

I also found an excel spreadsheet title calibtx.xls on a shareware site.

Try Vessels -> Volumes -> Vert. -> Hemisph. in the site below.
