Enter the modified Reynolds number into the Calculator. The calculator will evaluate the Packed Bed Friction Factor.

## Packed Bed Friction Factor Formula

fp = 150/Grp + 1.75

Variables:

- fp is the Packed Bed Friction Factor ()
- Grp is the modified Reynolds number

To calculate Packed Bed Friction Factor, divide 150 by the modified Reynolds number, then add 1.75.

## How to Calculate Packed Bed Friction Factor?

The following steps outline how to calculate the Packed Bed Friction Factor.

- First, determine the modified Reynolds number.
- Next, gather the formula from above = fp = 150/Grp + 1.75.
- Finally, calculate the Packed Bed Friction Factor.
- After inserting the variables and calculating the result, check your answer with the calculator above.
