*Total length of piping from outlet of first stage regulator to inlet of second stage regulator (or to inlet of second stage regulator furthest
away).
Notes:
1) To allow 2 PSIG pressure drop, multiply total gas demand by .707, and use capacities from table.
2 )
For different first stage pressures, multiply total gas demand by the following factors, and use capacities from table.
