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

Click For Summary
SUMMARY

The discussion focuses on calculating the mass flow rate of air flowing through a tube with a diameter of 40 cm at a velocity of 18 m/s, under conditions of 1 atm pressure and 32°C temperature. To determine the mass flow rate, one must first calculate the surface area using a radius of 20 cm, convert pressure to Pascals, and then apply the formula: mass flow rate (kg/s) equals force divided by velocity. This method provides a clear pathway to obtaining the mass flow rate based on the given parameters.

PREREQUISITES
  • Understanding of mass flow rate calculations
  • Knowledge of fluid dynamics principles
  • Familiarity with unit conversions, particularly pressure to Pascals
  • Ability to calculate surface area of a cylinder
NEXT STEPS
  • Research the formula for mass flow rate in fluid dynamics
  • Learn about the conversion of pressure units to Pascals
  • Study the calculation of surface area for cylindrical shapes
  • Explore the effects of temperature on air density and flow rate
USEFUL FOR

Engineers, physicists, and students studying fluid mechanics or aerodynamics, particularly those interested in calculating mass flow rates in various applications.

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
