Gas pipe sizing technique

[Dotty]

The gas training books in your drop box croppie do it this same method?

Erm. Dunno if I'm honest.

My lunch break education. So, according to my calculations with a U16 meter and these gas pipe sizes I am able to work on this install as it it less than 0.035.

It is the same method used in tolleys book.

I still don't understand in the viper book why they only x the last section by 2 to get the drop and not 3 like the rest of them?
