Would it be possible for anyone to define the term 'fan external static pressure'?
As I understand it this is the pressure generated by the fan as measured at the fan outlet, would that be correct?
Also, if that is the case, how would the 'AHU external static pressure' be derived? Would this be measured at the fan outlet within the AHU or at the outlet of the AHU itself? Thanks everyone - I appreciate your help!!
