Determining Flow Rate from a Closed Pipe

AI Thread Summary
The discussion revolves around determining the flow rate of water from a closed pipe connected to a tank. Initially, the user considered measuring stagnation pressure at the main pipe without accessing the outlet. However, participants pointed out that a truly closed pipe would not allow for any flow. The user clarified that the pipe is connected to the water mains and acknowledged the need for a flow meter to resolve the issue. Ultimately, the user found a solution by planning to install a flow meter on the pipe.

im trying top find the flow rate of water from a closed pipe.
one thing that i think i can work with is a hose.
there is a hose branching of the main flow pipe, which can be used to clean floor etc.

im thinking that i can not open the hose and thus measure the stagnatiob pressure at the main pipe.
i need help to find a flow rate from this.
any ideas?

If the pipe is closed there will be no flow.

Your problem description isn't clear, can you provide a more coherent explanation or better yet, a schematic/sketch?

totally agree with stewarcts. when the pipe is closed, that mean no flow, no acceleration but u has a volume.

Yeah sorry guys. By closed pipe i meant, the pipe is connected from the water mains to the tank, and i don't have an access to the outlet where i can measure the flow.

But the its algud now, I am in talks to put a flow meter on the pipe. so the problems solved, bt thanks anyways.

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 '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...

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
