... (cutoff – baseline) ranged from 8000 to 3000 PSI depending on the experimental condition. The cutoff of 10,000 PSI was used in experiments due to the pressure ranges of backpressure valve used in this study. It can be increased up to 20,000 PSI after upgrading to another back pressure regulator limit...
