An example of air pressure is the average sea-level air pressure of 101.325 kPA.
The reduced air pressure in the area caused heavy rain clouds to form.
The meteorologist continued to check the air pressure before the storm.
Should I use an air pressure control or a throttling valve to adjust pump speed?
This should give you a range from 0 to 45 minutes and is a definite consideration for those having trouble adjusting to the air pressure while falling asleep.
