Mass Flow Rate Through 40 cm Tube at 18 m/s

[Jacob87411]

If I know air is flowing through a tube with diameter of 40 cm at 18 m/s, with P=1 atm, T=32 C how do I find the mass flow rate..thank you

Before we can help you, you need to show some of your own thoughts. If you are still unsure where to begin, see if you can find out what "mass flow rate" means and what variables are required to calculate it.

find surface area w/ 20cm radius, convert to Pa, multiply to get F, divide by velocity will give you kg/s
