Column Volume Forumla
The following formula is used to calculate the volume of a column:
V = L * pi * D^2/4 /1000
- Where V is the volume (ml)
- L is the length (mm)
- D is the inner diameter (mm)
To calculate the column volume multiply the length by pi times the inner diameter squared, then divide by 4000.
Column Volume Definition
A column volume is defined as the amount of space taken up by the interior of a column.
How to calculate column volume?
To calculate column volume, first, determine the length of the column. For this example problem, we will use a length of 500 mm.
Next, determine the inner diameter. This can also be substituted for the inner radius, but the formula that would be used would slightly change to L*pi*r^2. For this example, the inner diameter of the column is found to be 20 mm.
Finally, calculate the column volume using the formula above:
V = L * pi * D^2/4 /1000
= 500*3.14159*20^2/4/1000
= 157.08 mL.
If you want to convert this further to display the result in liters instead of milliliters, divide the result above by 1000 again. This yields:
= 157.08/100
= .15708 L
