Question

4. If you double an axial fan's size (geometrically similar/scaled equally in all dimensions) and keep the rotational speed constant, the fan's flow rate in free air: a. b. c. d. e. Increases by a factor of 2 Increases by a factor of 4 Increases by a factor of 6 Increases by a factor of 8 Remains unchanged 5o hefolowin of sund Peseando sound Powern Sound Pressure is a point measurement of sound intensity, and Sound Power is an integral measurement of total sound energy Sound Pressure is what our ears sense Sound Power decreases with distance from the source Both (a) and (b) Both (a) and (c) (a), (b), and (c) a. b. c. d. e. f. Which more closely represents the response of a typical human ear, a measurement in sones or dBA? 6.

Explanation / Answer

4. Option e. Remains same. The flow rate and the efficiency of the axial fan doen not vary by changing the size of the fan.

5. option a. The sound pressure is the intensity of the sound and sound power is the summation of the sound energy.

6. dBA - decibels
