I'm having some trouble understanding this problem. It was a passage question. f=Av would bee used but why multiply by density of air?
If the speed of the air flowing through the cylinder is found to be 15 m/s, what is the mass of the air moving past any point in the cylinder each second?
The area is .005m^2 and density of air is 1.2 kg/m^3
The answer is 90 grams.
