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.
