How many BTUs can a 3/4 gas pipe carry?

Total piping length = 84 feet (use Table 3 @90 feet) From a to b, demand = 38,000 + 35,000 + 30,000 = 103,000 BTU/hr; use 3/4″ pipe From b to c, demand = 38,000 + 35,000 = 73,000 BTU/hr; use 1/2″ pipe or 3/4″ tubing From c to d, demand = 35,000 BTU/hr; use 1/2″ pipe or 5/8″ tubing From c to e, demand = 38,000 BTU/hr;.

What size gas line is needed for a gas range?
