Tank Volume Formulas
Vertical Cylinder
V = PI x r^2 x h
Where:
r = radius = D/2
h = liquid level
Horizontal Cylinder (Partial Fill)
Segment Area = r^2 x arccos((r-h)/r) - (r-h) x sqrt(2rh - h^2)
Volume = Segment Area x Length
Where:
r = radius = D/2
h = liquid level (from bottom)
L = tank length
Sphere (Partial Fill)
V = (PI x h^2 / 3) x (3r - h)
Where:
r = radius = D/2
h = liquid level (from bottom)
