Liquefied gas pipeline transportation, related to fluids

Does the H=10M in the friction along the way refer to the medium being delivered? Can the corresponding pressure be expressed as P=density? * 9.8 * H calculation? What is the unit of calculation?
Looking at your question, I think you must not have calculated the drag drop. 1. H=10M is the head, not the head of the pump. 2. Pressure cannot be used as P=density * 9.8 * H, this can be used to calculate the liquid level pressure, but the pipeline resistance drop is not based on this formula. Use software to calculate the resistance drop per 100 meters and then multiply it by the number of meters.
The friction along the way is the pressure head loss of the piped liquid. The unit can be m or Pa. The conversion relationship between the two is Pa=ρgh, where the unit of h is m.
