One can thus determine pressure differentials as a function of time.
New, smaller windows were used to prevent a possible blowout while operating at high pressure differentials.
This time she felt it move slightly, but the pressure differential was still too great, sucking the titanium piece firmly down onto its seat.
High pressure differentials integral mounting feet, and retrofit competitive units.
They can't withstand high pressure differentials and are only used in specialty applications.
They are good in wells that have high pressure differentials or large tubing load variations and can be set precisely.
An automatic valve allowed a maximum pressure differential of +2 lb.
The windows may also have a slight vibration due to the varying pressure differentials.
There's always a pressure differential through a jumpdoor.
On the other hand, in order to meet higher pressure differentials the stacks are operating with draft fans simultaneously.
