Calculate the speed with which a gas escapes from a container?

Click For Summary
SUMMARY

The discussion focuses on calculating the speed of helium escaping from a container under specific pressure conditions. The user inquires about the appropriate formula to determine the escape velocity of helium from container "A" at 2 atm pressure, compared to oxygen in container "B" at 1 atm. Key concepts include the mass flow rate, which is defined as the product of volumetric flow and the specific gravity of helium. The user aims to design a container with a valve for controlled helium release.

PREREQUISITES
  • Understanding of gas laws, particularly the Ideal Gas Law.
  • Familiarity with fluid dynamics concepts, specifically Bernoulli's equation.
  • Knowledge of mass flow rate calculations.
  • Basic principles of pressure differentials in gases.
NEXT STEPS
  • Research the Ideal Gas Law and its application in calculating gas behavior.
  • Study Bernoulli's equation to understand fluid flow and velocity calculations.
  • Learn about mass flow rate calculations in gas systems.
  • Explore the effects of pressure differentials on gas escape velocity.
USEFUL FOR

Engineers, physicists, and hobbyists involved in gas dynamics, container design, or anyone interested in calculating gas flow rates in pressurized systems.

Hi guys, (I apologize if I'm wrong here, and I apologize for my bad English but I'm Italian): if I have two container, where: container "A" (there is "He" with a pressure of 2 atm); container "B" (remember "O2" with a pressure of 1 atm). 1) you tell me which formula to use to calculate the speed with which the helium flows out from the container "A" ?? 2) if the two containers had the same pressure? P. S. : In fact I have to build a container (with helium inside). There will be a valve that will release the helium from the container. I have to calculate the mass flow rate (volumetric flow * specific gravity helium). But I do not know the speed, that 's why I am asking this. thanks so much
