1.   On a calm day, it can register a pressure difference across the thickness of the Handbook of Chemistry and Physics.

2.   This results in a pressure difference across the membrane.

3.   Conversely, the flow rate produced by a given pressure difference between the ends is much higher for laminar flow than for turbulent flow.

4.   In most experimental arrangements, it is the pressure difference, not the flow rate, that is held constant.

5.   Since the pressure difference across the boundary layer is negligible, the pressure at these holes is the static pressure p.

6.   An exceptionally strong pressure difference between a potent high over New England and low pressure over the Caribbean has caused a prolonged period of very windy weather.

7.   As the storm moves away and the pressure difference lessens, the seiche disappears.

8.   A formidable pressure difference between the low and polar high pressure over Ontario will promote gusty winds across the Northeast.

9.   A strong pressure difference between the intensifying Northeast low and a cold high-pressure center over central Canada will promote very gusty winds near the Great Lakes on Saturday.

10.   A strong pressure difference between high pressure over New Mexico and low pressure in western Canada will promote locally gusty winds from eastern Montana to eastern Colorado.
