Fair (paper presented at the AIChE Annual Meeting, Chicago, 111., November 1996) correlated data for efficiency reduction due to the rise of entrainment near entrainment flood, getting ln v = A + BO + CO2

where O is the fractional approach to entrainment flood and A, B, and C are constants given by
