Porous media coefficients and working fluid

  Hi all,
  
  I hope you all are doing well!
  I am wondering if the porous media coefficients will change if the working fluid changes.
  I have a tubular, U-shaped heat exchanger geometry where the working fluid is air.
  This model has been tested (experiments) in detail earlier, and its porous media coefficients have been estimated.
  Now I need to use the same heat exchanger geometry (for CFD), but the working fluid is replaced with water.
  Can I use the above porous coefficients for water?
  Kindly make your replies.
  Thanks in advance.

  I do not think do as pressure drop might change.
