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:
“Oh none too soon through the air white and dry
Will the clear announcer’s voice
Beat like a dove, and you and I
From the heart’s anarch and responsible town
Return by subway-mouth to life again,
Bearing the morning papers,”

“The method of painting is the natural growth out of a need. I want to express my feelings rather than illustrate them. Technique is just a means of arriving at a statement.... I can control the flow of paint: there is no accident, just as there is no beginning and no end.”
