The pressure drop through drill bit

Hi every body,In UBD case when estimate the pressure drop cross the bit nozzles there are a formula by William lyons to find that but I need to ask that the V mix the specific weight of fluid mixture under bottom-hole conditions (Ib/F^3) is any formula can I used to estimate this factor.My case UBD: water base mud + AirRegards, See More
