Although water may be raised 34 feet with a theoretically perfect pump and with a barometric pressure of 30 inches the actual limit is much lower.
With a fall of barometric pressure, the air in the cavity, being at a higher pressure than the external air, the air will flow outward and the well is said to exhale.
These effects are in almost every case due to variation of barometric pressure.
This has nothing to do with the vapor pressure (concave) curves, which are independent of barometric pressure, and consequently does not affect the solution of the previous problems.
To correct readings of the hygrometer for changes in barometric pressure: A change of pressure affects the reading of the wet bulb.
At the end of each barometer line will be found a fraction which represents the proportion of the relative humidity already found, which must be added or subtracted for a change in barometric pressure.
The chart applies at a barometric pressure of 30 inches, and, except for great accuracy, no correction is generally necessary.
But any such change in the temperature of the upper air would influence the lower air through changes in barometric pressure.
Changes in the load of the earth's crust due to erosion and the deposition of sediment, no matter how rapid they may be from the geological standpoint, are slow compared with those due to changes in barometric pressure.
A drop of an inch in barometric pressureis equivalent to the removal of about five inches of solid rock.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "barometric pressure" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
