WebApplying this to our original data where a water flow rate of 180 GPM resulted in a pressure drop of 45 inches water column, we could convert the pressure drop of 45 ”W.C. into 11.21 kPa and express the density as 1000 kg/m 3 to solve for a new value of k: WebA difference in ± 0.05 inches of water column of the recorded reading may indicate air velocity changes to your fume hood. Continuing to use a fume hood with high or low flow poses a risk to the user and lab occupants if the chemicals are not adequately contained and exhausted. ...
