### What is the assumed pipe material for the natural gas calculator?

Does anyone know what the default material/friction loss is used for the natural gas calculator? I assume it is steel from the results I am seeing but need to change it to HDPE, if possible.

Thanks!

Natural gas calculator is for up to 100 bar so it is surely steel pipe.

Thanks, is there any way to find out the actual friction coefficient the calculator uses? I am sizing an HDPE system and need to convert the results from the calculator to HDPE.

thanks for your reply

maybe this is the answer

but...

what is the geometrical significance of that multiplication
