Fluid dynamics of container of gas

Click For Summary
SUMMARY

The discussion focuses on calculating the rate at which gas exits a container through a hole, given a constant internal/external pressure differential. The exit rate is directly proportional to the pressure and the area of the hole, while it is inversely proportional to the square root of the molecular mass of the gas, assuming ideal gas behavior. A constant factor is also involved, which is relevant for typical ideal gases like air. The specific formula for this calculation is not provided but is essential for understanding gas dynamics in this context.

PREREQUISITES
  • Understanding of ideal gas laws
  • Basic principles of fluid dynamics
  • Knowledge of pressure differentials
  • Familiarity with molecular mass concepts
NEXT STEPS
  • Research the ideal gas law and its applications
  • Study the principles of fluid dynamics, focusing on gas flow through orifices
  • Learn about the calculation of flow rates in fluid systems
  • Explore the effects of molecular mass on gas behavior and flow rates
USEFUL FOR

Students and professionals in physics, engineering, and fluid dynamics, particularly those interested in gas flow calculations and applications in various scientific and industrial contexts.

Given a container with a gas, assuming a constant internal/external pressure differential, with a hole of a particular diameter/area, what is formula to compute the rate at which the gas exits the hole.

Assume we're talking ideal gas or air and anything else that I haven't given, but are needed.

You might also assume you're speaking to someone with little or no fluid dynamics under his belt.

it is inversely proportional to square root of molecular mass of the gas assuming ideal behaviour

and directly proportional to Pressure and Area of hole
 
Thanks.

I assume it would also include some constant. If so, what would the constant be for a typical ideal gas or air? Just getting it into the right ball park is fine - I'm not computing anything exact.
