) An air is drawn through the main 60 cm diameter supply duct of an air conditioning system. The velocity before the fan is approximately zero and the after the fan is 10 m/s. the pressure drop across the fan is such that the temperature change is negligible. Assuming the fan converts 85 percent of the electrical energy it consumes into kinetic energy of air. Determine a) the air mass flow rate b) the electrical energy required Take the density of air to be 1.20 kg/m³. 60 cm ) An air is drawn through the main 60 cm diameter supply duct of an air conditioning system.
