How to Calculate Industrial Fan Power: 6 Steps (with Pictures) - wikiHow

WebCalculate electric motors shaft power. Power is in general rated in watt (W) or horsepower (hp). The old imperial unit horsepower is equal to 746 watts (0.745 kW) or 33000 lb ft per minute (or 550 lb ft per second ). The unit of electric power - 1 watt - is equal to the power produced by an electrical current of 1 amp at a potential difference ... WebThe air leaves the fan through a duct at a velocity of 12m/s and a discharge static pressure of 8cm of water above atmospheric pressure. If the specific weight of air is 1.2kg/m3 and the fan delivers1 2m3/s, what is the fan input power to the motor if the fan has a mechanical efficiency of 70% and motor efficiency of 80%.
