Hi All,

 

I have a query w r t Fired Heater Forced Draft Fan Performance curves. I have a furnace for CDU which has combustion air FD fan .I am trying to simulate fired heater in hysys.

FD fan datasheet has curves in it as capacity in m3/ min vs static pressure in mm water column . Datasheet also mentioned that suction pressure is -30 mm water column and discharge pressure is 200 mm water column .In Hysys,  curves are put in the form of head vs capacity. I want to know how to convert static pressure in mm WC to head in m .? Request your help with detailed explanation.
