(41) Bulk Cylindrical Tank

Hi, Thomas Klemm

I define f(x) this way because the curve can be fit nicely as a straight line.
With your corrected V(x), f(x) plot appeared amazingly straight

With slanted bottom 30% full or more, a very simple rule-of-thumb can be used.

V_b = Pi r^2 h f(x) ~ Pi r^2 h (57% (h/h0) - 7%))

Example, for h=8", h0=12", r=72", effective height = 8 * (57% (8/12) - 7%) = 2.48"

V_b = Pi * 72² * 2.48 = 40389 in^3 = 175 gallons (match post #27)
