This can be used to model a discharge flange, or discharge head ( equipment ). Kv_si is the SI equivalent of Kv ( CGS?/metric ) or Cv ( US ). If you have a 'K' value it can be converted into a Kv or Cv by using the formulas documented in TP410, see here for a calculator: http://flowoffluids.com/calculators/k,-cv-kv-conversion.aspx Kv_si = Cv * 1316182.677552736714218848847087 Kv_si = Kv / ( 3600 * sqrt( 100000 ) )
