    Altitude Gas
AI Thread Summary
A cylinder filled with compressed air at 2,000 psi leaking at 1 liter per minute at sea level will maintain the same leak rate at an altitude of 8,000 feet. The flow is choked, meaning that changes in outlet pressure due to altitude do not affect the flow rate. The discussion emphasizes that the problem is straightforward and not homework-related. The original poster expresses gratitude for the responses and clarifies their non-technical background. The conversation highlights the principles of gas flow under varying pressure conditions.

I have a (faulty!) cylinder filled with compressed air at 2,000 psi which leaks at a rate of 1litre/minute at sea level. What would be the expected rate of leak at an altitude of 8,000ft? thanks for your help.

Sounds like homework, perhaps you had better show some attempt at a solution before we help you...
 
Um... I don't see this as homework because the answer is way too simple. The answer is there's no change in flow rate. The flow is choked so there's no increase in flow with a decrease in outlet pressure.
 
thanks for your replies and apologies if it was posted in the wrong place. just a non-technical person, with a problem, stubbled on the website and hoped i could get a reply...

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
