Pipeline De-watering

Any Ideas on how to calculate speed of a pig being used to de-water a pipeline that was previously filled with water?

Given that the pig is being pushed with an air compressor with a maximum operating pressure of 150 psi and flow rate of 150 CFM at 60 psi. If line is 6" in diameter and over 10 km long, would a larger compressor be more suitable for the job. If so, how would one determine the pressure needed to push the water out of the line. I want to be able to do this so that it doesn't take an insane amount of time to do, and also for my own curiousity.
