Calculating resistance coefficients for the porous media

  Hello,
  
  Was referring to ANSYS Help regarding how to calculate the coefficients (https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v195/aim_all/AIM/user_manual/aim_boundary_conditions/fluids/topics/c_flu_bc_porous_media_curve_fit.html).
  
  So we may plot pressure drop against flow velocity in Excel, to get a trendline equation for a second order polynomial fit. Then, calculate the viscous and inertial resistance factors based on the coefficients from the fitted curve, correct?
  
  With reference to the two circled areas in the attached image, could you please clarify whether:
  1. Should the units for C1 be 261996 [m^-2] instead?
  2. Should C2 be equal to 0.4472 [m^-1] instead?
  Kind regards,

  In the Discovery Tutorial "air intake - porous media", an Excel sheet to calculate resistance coefficients is mentioned.
  Where can I find this Excel sheet?
