What does the sound in a pipe sound like when the gas flow rate is 40 m/s? !
Thread Content
The gas flow velocity is 40 m/s, which is quite high in the pipeline. What does the sound inside the pipe sound like at this time? Is it a very sharp sound, like an air-raid alarm? !
It’s probably the vent of the pipeline that’s making a lot of noise.
It’s so difficult to describe sound in words: lol but for one thing, to eliminate sound, it’s possible to wrap glass wool or something similar around the pipes.
Are you sure? The flow rate in the exhaust pipe is 15 m/s, and the noise is quite loud.
It’s so much beyond the normal flow rate – what are you trying to do? When it exceeds that limit, pulses are generated, and the force involved is terrifying; you can’t even imagine how strong that force is: lol
Really? How scary is it? ! It still hasn’t reached the speed of sound in a fluid. The safety valve’s discharge performance is just average!
There is no sound inside the pipeline; for overheated steam, a recommended flow rate is of 40–60 m/s. However, no significant sound is heard during operation, probably due to the insulation layer absorbing the sound. However, superheated steam makes a loud noise when it is vented, so a silencer is necessary; this is due both to the flow velocity and to the expansion that occurs as pressure drops.
Is it under normal operating conditions or in a release mode? If noise reduction is required, insulating material should be used.
We have a setup with 4000 Nm3/h and pipes of 200 mm in diameter; please calculate what that amounts to. The exhaust stack you mentioned is not the same thing
