I need to calculate the pressure drop for a 2 phase flow application for a check valve. I would normally calculate the combined density and calculate pressure drop based on total combined flow. Are there any other practical and simple ways to accuratly calculate the pressure drop?
 
What kind of conditions? I've put dP gauges across a bunch of check valves in pretty rough conditions and the dP (after lift) is always too close to zero to be read on a +/- 5 psid gauge. I'd use the k-value from Crane 410 (i.e., either 50 f(t) or 100 f(t)) and convert it to a length of straight pipe.
