Air Pressure & Air Flow
Air pressure is most important for cooling. It indicates cooling power per unit area. If the diameter of a fan is constant, then more air pressure indicate more air flow. Simple relation of air flow with air pressure is, (dia*dia)*(air pressure*air pressure)/(100*28.51875)= Air flow (in CFM) Here, dia in mm(diameter of fan), air pressure in mmH2O

Famous quotes containing the words air, pressure and/or flow:
“I moved like a lobster,
slower and slower.
The air was tiny.
The air would not do.”
—Anne Sexton (1928–1974)
“Today’s pressures on middle-class children to grow up fast begin in early childhood. Chief among them is the pressure for early intellectual attainment, deriving from a changed perception of precocity. Several decades ago precocity was looked upon with great suspicion. The child prodigy, it was thought, turned out to be a neurotic adult; thus the phrase “early ripe, early rot!””
—David Elkind (20th century)
“Reminiscences, even extensive ones, do not always amount to an autobiography.... For autobiography has to do with time, with sequence and what makes up the continuous flow of life. Here, I am talking of a space, of moments and discontinuities. For even if months and years appear here, it is in the form they have in the moment of recollection. This strange form—it may be called fleeting or eternal—is in neither case the stuff that life is made of.”
—Walter Benjamin (1892–1940)
