Natural Gas Flow Rate Increase
Natural Gas Flow Rate Increase
(OP)
Im a EE with a generator that consumes 987 scfh of natural gas with a minimum operating pressure of 7"WC and a max operating pressure of 13.6"WC. The regulator feeding the gas line is set at 7"WC and the equivalent run to the gen is roughly 170 ft. By looking at the tables with standard assumptions; pressure less that 1.5 psig, .5"WC pressure loss, .6 specific gravity for nat gas, sched 40 steel pipe, it says that I can get 971 scfh. If I increase the pressure to 11"WC, which happens to the be next seeting of the reg, will that be enough to provide the flow I need. The mechanic on the job insist that it will work. What formula(s) should I use to figure this out. I dont want to just assume it will work. Thanks.

Is your lenght actual or does it include equivalent lenght with fittings?.
I get .56 inches H2O drop for 2in sch 40, .24 inches for a 2.5 inch sch 40 and a 1.9 inch drop for a 1.5 inch sch 40 line.
that means you need 2 inches H2O of water extra to use a 2" line versus a 2.5 inch line.
