WebFEGs are based on peak total efficiency for a given fan size. The FEG is established by plotting the peak total efficiency at the appropriate impeller diameter, then reading the associated FEG band in which this point falls. For example, a fan with an impeller diameter of 15 in. and a peak total efficiency of 71% would have an FEG of 80 (Figure 3). WebBasic Fan EquationsFig. 1 •TP = VP + SP (in.

Losses between AHP and BHP can be attributed to skin friction, turbulence, leakage, and mechanical friction. So, total efficiency can also be expressed as a culmination of hydraulic, volumetric, and mechanical efficiency. Ƞ t = Ƞ h x Ƞ v x Ƞ m. pipe to water trees
