How Target Volume Height Calculator Works?
To solve for height, the Target Volume Height Calculator divides the target volume by the circle area of a chosen tube. The process takes 4 steps.
Enter the target volume
Type the concrete volume in cubic feet (ft³), cubic yards (yd³), liters (L) or cubic meters (m³).
Pick the tube diameter
Select a stock size from 6 in to 24 in, or type a custom diameter.
Divide by circle area
The calculator finds the circle area and divides the volume by the area.
Read the height
The result appears in inches (in), feet (ft) and centimeters (cm). Compare it with the frost depth and the form length.
Target Volume Height Calculator Formula
The Target Volume Height Calculator rearranges V = π × r² × h to isolate the height.
Height
h = V ÷ (π × r²)V in ft³ and r in ft gives h in ft.
Height in inches
h (in) = 12 × V (ft³) ÷ (π × (D ÷ 24)²)D is the diameter in inches.
Fill per foot
k = π × (D ÷ 24)²k is the ft³ held by 1 ft of tube.
Worked example: 2 ft³ of concrete in a 10 in tube
- k = 3.1416 × (10 ÷ 24)² = 0.5454 ft³ per ft
- h = 2 ÷ 0.5454 = 3.667 ft
- h = 44.0 in (111.8 cm)
Target Volume Height Calculator Conversion Table
The target height conversion table shows how tall 6 tube sizes fill with 1, 2, 3 and 5 ft³ of concrete.
| Tube diameter | Height for 1 ft³ | Height for 2 ft³ | Height for 3 ft³ | Height for 5 ft³ |
|---|---|---|---|---|
| 8 in | 34.4 in | 68.8 in | 103.1 in | 171.9 in |
| 10 in | 22.0 in | 44.0 in | 66.0 in | 110.0 in |
| 12 in | 15.3 in | 30.6 in | 45.8 in | 76.4 in |
| 16 in | 8.6 in | 17.2 in | 25.8 in | 43.0 in |
| 18 in | 6.8 in | 13.6 in | 20.4 in | 34.0 in |
| 24 in | 3.8 in | 7.6 in | 11.5 in | 19.1 in |
1 ft³ equals 28.3 L, or about 1.7 bags of 80 lb concrete.
What is Target Volume Height Calculator?
A Target Volume Height Calculator is a reverse cylinder calculator that finds how tall a set volume of concrete stands inside a chosen tube diameter.
The calculator answers depth questions. A crew with 3 ft³ of concrete and a 12 in tube fills 45.8 in of height. A designer with 3 ft³ and a 10 in tube learns the pier must be 66 in deep.
The result helps decide form length. Tubes sell in 4 ft and 12 ft lengths at most stores, and the height result shows which length to buy.
What are the uses of Target Volume Height Calculator?
There are 4 main uses of the Target Volume Height Calculator.
Form length selection
Buyers match the height to a 4 ft, 8 ft or 12 ft tube length.
Depth design
Designers set pier depth for a specified volume and diameter.
Batch matching
Crews see how far one mixer batch rises in a given tube.
Frost depth checks
Builders confirm the computed height reaches below the local frost line.
