Pipe kw carrying capabilities

[Devonplumber]

Evening gents I have been trying to work out pipe loads but have be unable to find any formula or charts to help. Can anyone tell me the kw carrying capabilities at 1.5ls with 20c drop on 35mm,42mm,54mm,2.5"'3",4"?

any reason why?

isn't this normally left to mechanical engineers design specs?

I have been fitting biomass for 3 years and want to move on to design but everyone you ask doesn't want to tell you wait they already know.
