decide volume fraction(vf) at air inlet in multiphase flow, Qa = air flow rate, Qw = water flow rate

I am injecting air over plate over which water is flowing(see domain attached), since vf = Qa/(Qa+Qw), Qw and vf are known through this Qa is calculated, and since air inlet dimension is known so...
