How is gas flow rate estimated?
Thread Content
The nitrogen pressure is 0.3 bar, the pipe diameter is 22*2; how can the flow rate be estimated? I seek advice from experts.
To find the flow rate of nitrogen, it can be calculated
The flow velocity inside the pipe shouldn’t be too high; let’s assume 8 m/s.
If calculated at 8 m/s, the flow rate Q = area * flow velocity = 0.018*0.018*3.14*8/4 = 7.3 cubic meters per hour, right?
Yes, I forgot to write it above, but the result is correct. If I calculate the nitrogen consumption and convert it to standard cubic meters, do I still need to multiply by 1.3?
Because the gas pressure is 0.3 bar, converted to standard atmospheric pressure under normal temperature conditions
Search on Baidu to find out what \"subscript\" means.
8 meters is too small; with 0.3 barg, you should be able to reach at least 10 meters.
Moderator, how is this flow rate estimated? But I want to cover 8 meters in one second – that’s already a very fast speed; in the time it takes to blink, one is already 8 meters away.
