Air pressure and wind - National Weather Service
www.weather.govWind results from a horizontal difference in air pressure and since the sun heats different parts of the Earth differently, causing pressure differences, the Sun is the driving force for most winds. The wind is a result of forces acting on the atmosphere: 1. Pressure Gradient Force (PGF) - causes horizontal pressure differences and winds 2.

Vapor Pressure - National Weather Service
www.weather.govThen, saturated vapor pressure (e s) and the actual vapor pressure (e ) can be calculated using the formula listed below: e = 6.11 × 10(7.5 × T d 237.3 + T d) e 6.11 10 s = × (7.5×T) 237.3 + T For a bonus answer, after calculating both vapor pressures the relative humidity (r h)

www.rses.orgimpacts the pressure drop and service life of a filter, but can also impact filter efficiency. If a panel filter is underrated, its overall efficiency on larger particles may actually be reduced. This is because most lower MERV filters utilize impingement as the main capture mechanism.
PRESSURE-ENTHALPY CHARTS AND THEIR USE - RSES
www.rses.orgIn refrigeration service work, gauge pressure (psig) is generally used. On a pressure-enthalpy diagram, however, the pressure is shown as absolute pressure (psia.) The difference between the two is about 14.7 pounds per square inch or about 30 inches of mercury (29.92 inches of mercury, to be more precise).
