On the dynamic pressure issue of gas delivery through horizontal pipes

It’s likely that no one can answer your question; firstly, your understanding of the concepts of pressure loss and drop is incorrect, as the cause of pressure drop is actually pressure loss itself. Secondly, the pressure for pipeline transportation in your case is unknown; the calculation methods vary for high pressure, medium pressure, and low pressure. It is recommended that you consult the calculation formulas in the town gas design codes and carry out the calculations based on your delivery pressure.
