Velocity of escaping gas while depressurizing a tank

Click For Summary
SUMMARY

The discussion focuses on calculating the velocity of gas escaping through a valve in a tank pressurized at 2 psig. It confirms that the velocity can be estimated using Bernoulli's equation, specifically the formula p = 1/2 ρ V², where p represents the pressure, ρ is the gas density, and V is the velocity. The area of the orifice is also essential for accurate calculations, as it directly influences the flow rate of the escaping gas.

PREREQUISITES
  • Understanding of Bernoulli's equation
  • Knowledge of fluid dynamics
  • Familiarity with gas properties at different pressures
  • Ability to calculate orifice area
NEXT STEPS
  • Research how to apply Bernoulli's equation in practical scenarios
  • Learn about gas density calculations at varying pressures
  • Explore orifice flow equations and their applications
  • Investigate pressure loss in gas flow systems
USEFUL FOR

Engineers, physicists, and anyone involved in fluid dynamics or gas flow calculations will benefit from this discussion.

HI, anyone know how to calculate the velocity of a gas escaping through a valve in a rank ? The gas is pressurized at 2psig and I can get the area of the orifice if necessary.


Thanks.

The velocity is roughly equal to what Bernoulli's equation would predict, converting static pressure to velocity pressure.

p=1/2 rho * V^2
