#question# How to calculate the network with a low pressure

I am writing to ask if anyone know how to use morgen to deal with the natural gas pipeline network under low pressure environment (2kPa~10kPa).

According to https://doi.org/10.1186/s13362-021-00109-4, the units for pressure and mass-flux are set as [Bar] and [kg/s] to homogenize scales. So there are some difficulties when we have to deal with end-consumption scenarios like neighborhoods or business districts.

Besides, compressible fluids may follow different equations of state to describe their behavior. There can be significant differences in the computation of compressible fluids, such as natural gas, when different boundary pressures are involved.

Attached is the minute data of gas pipeline pressure in a business district.
