In our hydrotesting guidelines it is suggested that the engineer calculate the percent of entrained air in the pipe (6-30" hydrocarbon pipeline). I'm attempting to simplify and standardize our hydrotesting program, but I can't seem to find any method for determining the percent of entrained air. I understand it will involve the deviation of the pressure vs volume curve from the ideal pressure volume curve for pure water, but thats about as much information as I have. Any help would be greatly apprieciated.
Thanks
