A fan discharges 265 cu.m/min of air through a duct of 92 cm in diameter against a static pressure of 0.022 m of water. The fluid density is 995 kg/cu.m., the air temperature is 29°C and the barometric pressure reading is 730 mm Hg. If the power input to the fan is measured 3.5 hp, what are the total and static fan efficiencies?
