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.
 

Thread 'A practical way to vaporize fuel for high MPG?'

Here's a video by “driving 4 answers” who seems to me to be well versed on the details of Internal Combustion engines. The video does cover something that's a bit shrouded in 'conspiracy theory', and he touches on that, but of course for phys.org, I'm only interested in the actual science involved. He analyzes the claim of achieving 100 mpg with a 427 cubic inch V8 1970 Ford Galaxy in 1977. Only the fuel supply system was modified. I was surprised that he feels the claim could have been...

Thread 'Turbocharging carbureted petrol 2 stroke engines'

Hi everyone, online I ve seen some images about 2 stroke carbureted turbo (motorcycle derivation engine). Now.. In the past in this forum some members spoke about turbocharging 2 stroke but not in sufficient detail. The intake and the exhaust are open at the same time and there are no valves like a 4 stroke. But if you search online you can find carbureted 2stroke turbo sled or the Am6 turbo. The question is: Is really possible turbocharge a 2 stroke carburated(NOT EFI)petrol engine and...
