Fans - Efficiency and Power Consumption - Engineering ToolBox
WebInput Horsepower to the Electrical Motor. The input horsepower to the electrical motor for a pump or fan can be expressed as: P hp_el = P bhp / η e (3) or. P hp_el = (m h g / 33000) / (η η e) (3b) where. P hp_el = input … WebThe fan efficiency is the ratio between power transferred to airflow and the power used by the fan. The fan efficiency is in general independent of the air density and can be expressed as: μ f = dp q / P (2) where. μ f = fan efficiency (values between 0 - 1) dp = total pressure … L N = sound power level from fan (dB) S = rated motor power (kW) p = fan static … P AHP = Air Horse Power (hp) q = air flow (cfm) SG = Specific Gravity Air (= 1.0) … Fan Inlets - Air Density vs. Suction Pressure - High suction pressure at a fan inlet … It is important that a fan motor is capable to run the fan at the operating conditions - … Related Topics .
