Volumetric flow rate calculation.
Thread Content
Experts, please help. Given that the volume of the pipeline is 100 M3, the inner diameter of the inlet is 45 mm, the pressure in the pipeline is 40 map(a), and the operating temperature is 40°C, what flow rate is required at the inlet to fill the pipeline volume within 15 seconds? I hope the calculation process can be provided. And indicate the unit. Medium: Natural gas.
It’s a question that high school students can answer; I don’t see what the original poster is questioning ? ? With a volume of 100 m3, if it’s supposed to be filled in 15 seconds, what do you think the flow rate should be? 100×3600/15=240000 m3/h; in any case, with the 15 seconds you have in mind, such a high flow rate is necessary. Then consider the flow velocity; flow rate/pipe cross-sectional area = 41938 m/s, which is an impossible value for flow velocity. So, the original poster is talking nonsense and making random assumptions.
What the hell is 40map(a)A? Some idiot who knows nothing yet dares to create questions to test experienced teachers
……It’s the culture of taking from others; one has to reach out for everything
40 MPa – that’s a bit high
