How is the gas flow rate calculated during pipeline purging?
Thread Content
During pipeline purging, the pipeline flow meter was removed and replaced with a bypass. It is known that the pressure at the gas inlet of the pipeline under purge is 3.0 MPa, while the pressure at the outlet is 0.3 MPa. Can the gas flow velocity within the pipeline be calculated? What is the formula for calculation?
With nothing better to do, I calculated it according to the requirements given; it’s for reference only
The value calculated in the above figure is only the instantaneous outlet flow velocity. The flow velocity within the pipe is to be calculated
The first graph shows the instantaneous flow velocity at the pipe outlet, while the second graph shows the flow velocity inside the pipe. For reference only. We can communicate via WeChat
