A fan uses a rotating blade to moves 2m3 of air each second at a speed of 3 m/s. Assumes air is initially at rest and has a density of 1 kg/m3. Fans are inefficient; assume an efficiency of 10%. What is the acceleration of the air? m/s2 What is the mass of the air? kg What is the force the fan applies? N What is the power output of the fan? W What is the power input of the fan?
