Given the pipe diameter, pressure difference, and material composition, can the flow velocity or flow rate be determined?
Thread Content
As the title suggests, given the composition of the gas stream, the pipe diameter, and the pressure difference from the high-pressure side to the low-pressure side, is it possible to determine the flow rate? This question has been bothering me for a long time; I hope someone experienced can help answer it
Knowing the inner diameter of the pipe, will ignoring the pipe wall resistance in the gas phase allow an accurate calculation of the flow velocity?
What I know tells me that it’s not possible; I need to know things such as the discharge coefficient of the throttle device and its orifice size
When the operating conditions of the system are known, the system flow velocity can be determined based on the pipe diameter; there are corresponding tables available for this, or it can also be calculated directly. Of course, this is only the economic flow rate; many correction factors need to be adjusted to determine the exact value. The results calculated using simple empirical formulas will be far lower than the measurements from actual projects. There are many factors to consider. In short: knowing only these few factors can also help determine traffic, but the errors will be quite large.
