Calculating Pressure Drop in a Fume Hood System
WebApr 10, 2014 · This is actually a “head loss” which is equivalent to a pressure loss, or pressure drop. There are two forms of pressure loss: “major losses” and “minor losses.” In this case the term “minor loss” is actually a misnomer as it constitutes most of the pressure loss in a typical fume hood system. 2. “Major Losses” These are the ...
