天然气管道在输送天然气的时候,它内部压力是恒定的吗? 比如我随便取一节正在输气的管道研究,那么这根管道前端进气口跟后端出气口压力是一样的吗? 我听说只有两端有压力差,气体才会流动? 如果进气口跟出气口压力一样,那气体是无法流动是吗?

还是那句老话,建议看看化工原理这本书——流体力学

与其脱离实际幻想,不如利用学校联系燃气单位去做短期体验。

建议还是脚踏实地,把理论上的基本功练扎实了再去考虑实验的问题吧。尤其是对化工这个行业更要慎重。否则会出事故的、浪费资源,,,,,,供参考。

不是我并不是要做实验去实现这个过程,只是想了解一下咱们正常天然气管道在输气的时候,随便取其中一节管道,比如10m,那么这10m管道内压力都是一样的吗?

不一样啊。否则没有推动力了。
