Division 2.2 Calculation of the Fluid Dynamic Efficiency (FDEhood)

United Kingdom

The Fluid Dynamic Efficiency (FDE_hood ) at the best efficiency point is calculated by the following formula, and is rounded to the first decimal place:

{FDE}_{hood} = \frac{Q_{BEP} \times P_{BEP}}{3600 \times W_{BEP}} \times 100

Where:

Q_BEP is the flow rate of the domestic range hood at best efficiency point, expressed in m³/h and rounded to the first decimal place,
P_BEP is the static pressure difference of the domestic range hood at best efficiency point, expressed in Pa and rounded to the nearest integer,
W_BEP is the electric power input of the domestic range hood at the best efficiency point, expressed in Watt and rounded to the first decimal place.
