two phase mixture density equation
(OP)
Dear Professional
I would like to bother you a triaval how to derive the two phase density formula.
I try to derive from this formla
Two phase density = (weigh of liquid + weight of vapor)/[weight of liquid/liquid density + weight of vapor/vapor density]
to another formula as following
two phase density = [100/(100-%flash)]/Liquid density + %flash/vapor density
But I can't get this result
Can anyone give me an kindly help?
Thank you for any help.

RE: two phase mixture density equation
You require the hold up for both gas and liquid phase:
Hl = liquid hold up
Hg = 1- Hl - Gas hold up
labda l = Ql / (Qv+Ql) = no slip hold up, with Ql is liquid flow/volume and Qv is total volume/flow
labda g = Qg / (Qv+Qg)
Calculation of the mixture density is then given by
rho mixture = (rho l * labda l ^2)/Hl + (rho g * labda g ^2)/Hg
