Thank you very much for your assistance in this matter. It is greatly appreciated.
I have not yet acquired a pitot tube. Could you recommend one that could easily be connected to my Comark manometer.
Unfortunately, it is near impossible to gain access to the exhaust intake (there is only 1). Would a pitot transverse test through multiple areas of a straight section of duct be accurate. If so, could you enlighten me as to which is the most cost effective item with which to do this?
I have a...
So if the fan is a roof mounted exhaust fan (no duct thereafter), wouldn't the discharge side static pressure basically be at atmosphere? If so, would the fan curve be applicable?
A new centrifugal type exhaust fan is installed to a duct system with any dampers fully open. With the fan (DOL) operating, the static pressure measured in the duct on a manometer is 300 pascals. Plotted on the applicable fan curve, this equates to a volume flow rate of 1800 litres/sec. A volume...
