Friction Factor for Wetted Wall Columns

  1. Aug 11, 2015 #1

    I encountered this problem that asked for the friction factor of a very dilute SO2-air gas mixture in a wetted wall column. All the necessary information were given to compute for the Reynold's number. What I want to know is does having a wetted wall make it a different case (ergo use different set of formulas) compared to flowing in a typical steel pipe?

    Thanks a lot!

    Is the gas velocity zero at the interface with the fluid in the wetted wall column (as it is in a dry cylinder)?
