nV(D) dD = the volume of particles per cm3 of air having diameters in the range D and D + dD (here dD is an infinitesimally small increase in diameter) and therefore nV(D) = D3 nN(D) /6 Here nV(D) is in m2cm-3 Thus the total aerosol volume V per cm3 of air is = D3 nN(D) dD =nV(D) dD Here V is in m3 cm-3
Which statement accurately describes the relationship between air pressure and air density?
- Which statement accurately describes the relationship between air pressure, air density, or altitude? As altitude increases, pressure increases. As altitude increases, air density increases. Air pressure and density are lowest at sea level. Denser air exerts more pressure than less dense air. Denser air exerts more pressure than less dense air.
What is the relationship between air volume and air pressure?
- As show in following fig, when the fan in its rated rotation speed, the air volume and air pressure change as curve 1, which intersects with the pipe network resistance curve 2 at the rated working condition point N when the air door is full opened; the air volume of the fan is Qn and the pressure is Hn.
What factors affect the distribution of air pressure?
- Horizontally the distribution of air pressure is influenced by the temperature of air at a given place. In areas where temperature is high the air gets heated and rises. This creates a low-pressure area. Low pressure is associated with cloudy skies and wet weather. In areas where temperature is low, the air is cold and heavy.
How does volume affect the density of air?
- Explanation: Density is mass over volume. As volume increases density therefore decreases. Charles's law states that temperature and volume are directly proportional therefore as temperature increases, volume increase and density decrease. An increase in moisture content will decrease mass of an air mass.
