Cylindrical Horizontal Tank with One Hemispherical End

For the Cylindrical Horizontal Tank with One Hemispherical End, the gauge reading is converted to the total observed volume using the following equation.

Where:

R = Tank radius, length units

H = Gauge reading, same length units as R

L = Tangent-to-tangent length, same length units as R

V1 = Total observed volume of the main cylinder for gauge reading

Vs = Total observed volume of hemispherical end for gauge reading

V = Total observed tank volume at gauge reading

EXAMPLE: Cylindrical Horizontal Tank with One Hemispherical End

The cylinder tank with hemispherical ends has the dimensions of 7ft in diameter and a tangent-to-tangent length of 20ft. What is the total observed liquid volume for a gauge of 4ft 3in?

Vs = 59.11 ft3

V1 = 489.33 ft3

V = V1 + Vs = 548.44 ft3 = 97.62 bbls

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