Hi All,

One school taught me (in G3) that to size the pipes or tubing going from the manifold to the individual loads, you use the correct table for the material/fuel/pressure, and *that *individual load, along with the length *from that load to the gas meter*, thus including the length it is travelling in the manifold.

The other school (currently for G2) is saying that the individual length is only from the load to the manifold - which makes more sense to me because I consider the manifold to be the "source" extended out from the meter, and the manifold is sized to deliver a maximum certain amount of gas *from anywhere along its length*. And, the only time you include length of the manifold is during the sizing of the manifold using the LMR to the furthest load from the meter.

How was everyone taught?
