Enter the column length and the particle diameter into the L/dp Ratio Calculator. The calculator will evaluate the L/dp Ratio.

## L/dp Ratio Formula

The following two example problems outline the steps and information needed to calculate the L/dp Ratio.

LDP = L / DP

Variables:

• LDP is the L/dp Ratio (length/diameter)
• L is the column length
• DP is the particle diameter

To calculate the L/dp ratio (length to diameter ratio), divide the column length by the particle diameter.

## How to Calculate L/dp Ratio?

The following steps outline how to calculate the L/dp Ratio.

1. First, determine the column length.
2. Next, determine the particle diameter.
3. Next, gather the formula from above = LDP = L / DP.
4. Finally, calculate the L/dp Ratio.
5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variables as an example problem to test your knowledge.

column length = 3

particle diameter = 5

LDP = L / DP = ?
