(41) Bulk Cylindrical Tank

[Albert Chan]

Hi, David Hayden

If I am not mistaken, v0 = Hatch ht, R = Hatch depth.
It can be deduce from overflow check (LBL 07 ...), which required actual tank dimensions.

R were not computed, but graphically fitted (say a compass)
(Unless the dome is actually spherical cap, no such R exist)

In Figure 25-5, if you draw an arc (radius R), spherical cap volume ~ dome top volume.
(cross section area approximately equal, thus volume too)

Hi, Geoff

I also think the author dome top calculation were flawed.
(Not the formula, but how graphical fitted R was performed.)

Figure 25-5 implied R is from center to the dome edge.
If true, this implied height of cap = 78 - sqrt(78² - 72²) = 48 inches.
Since v <= v0 = 36 inches, the formula can never reach full capacity.
