RT, who calculates the flow velocity at the end of the pipeline? Are there any standards or formulas for this? Because the flow velocity at the end of the pipeline is needed to determine the performance requirements for the water pump and air compressor.
Flow velocity at the end of the pipeline? The flow velocity in a pipeline can be easily calculated using the continuity equation, as long as the flow rate and pipe diameter are known. Personally, I think the poster is asking for the pressure at the end of the pipeline?
Right, that Bernoulli equation – can it be used based on volume, flow rate, and cross-sectional area?
Sure. The flow velocity calculated in this way represents the average flow velocity across the pipe cross-section. For incompressible fluids, no corrections are generally necessary, while for compressible fluids, corrections must be applied
I recommend that you take a look at HG/T 20570.7 for pipeline pressure drop calculation
The 1995 version? Do you have 1995 (R2009)?
What is R2009? I have the 1995 version
There was something online about re-approval in 2009 or something like that, so I searched on Baidu. It’s from 1995; I’ve already downloaded it. Thank you! I’m not very familiar with this area. In other words, I need to use a pump to flush the pipeline, which has several bends in it, and I want to know what the flow rate of water is at the end of the pipeline. The pump is on the ground, with the pipes several meters above the ground. Using this standard for the first time, learning*learning*. . .
The flow rate through a pipe is the same at its inlet and outlet; if the diameters at the inlet and outlet are equal, then the flow velocity is also the same (only for incompressible fluids). If you are calculating a pump system, it is recommended that you also read Part 5 of this standard, \"Calculation of System Characteristics of Pumps and Determination of the Relative Installation Height of Equipment.\"
It seems like there’s a lot of content; is there a simpler way? Specific chapters. . . :dizzy:
