WebThe rule of thumb for cooling electrical equipment is 100 cfm (2.8 m 3 /min) per kW of losses. When the efficiency of the motor is known, the simplified calculation is: hp x 0.746 = kW. (1 – efficiency) x kW = losses. Losses x 100 = cfm recommendation. Rounding up by as much as 25% is prudent to ensure there is adequate air flow to cool a ... Web19 de set. de 2024 · How to Calculate Fan Efficiency. The efficiency of a fan as an energy converter is determined by the ratio of its output to the input power: \eta =\frac {P_ {out}} {P_ {in}} Input power delivered to a fan is: P_ {in}=V\times I. V and I are the electrical voltage (in Volts) and amperage (in Amps). P is measured in Watts.
