Cylindrical Vertical Tank with Hemispherical End

For the Cylindrical Vertical Tank with Hemispherical End, the gauge reading is converted to the total observed volume using the following equations.

For H £ R

For H > R

Where:

R = Tank radius, length units

H = Gauge reading, same length units as r

Vv = Total observed volume of the main cylinder for gauge reading

Vvh = Total observed volume of hemispherical end for gauge reading

V = Total observed tank volume at gauge reading

ClosedEXAMPLE: Cylindrical Vertical Tank with Hemispherical End

The cylindrical vertical tank with a hemispherical end has the dimensions of 7 ft in diameter. What is the total observed liquid volume for a gauge of 4ft 3 in?

For H > R

Vv = 28.88 ft3

Vvh = 89.85 ft3

V = 28.88 + 89.85 = 118.83 ft3 = 21.14 bbls

The cylindrical vertical tank with a hemispherical end has the dimensions of 7 ft in diameter. What is the total observed liquid volume for a gauge of 3ft 0 in?

H ≤ R

Vv = 0 ft3

Vvh = 70.73 ft3

V = 0 + 70.73 = 70.73 ft3 = 12.59 bbls

See Configuring - Cylindrical Vertical Tank with Hemispherical End for details on how to configure this tank type.
