quick gas capacity question

Good grief. Does anyone read the original post?

And no, its not 70Mbar lol

From a gas flow point of view you need to advise the diameter of the supply gas main ("big enough" isn't very informative), the length of 1" and 3/4" take of lines (plus elbows etc) and the diameter of the outlet nozzle from which you'll be drawing the gas, since flow rates will be dependant on the friction loss. Once that information is available there are fairly standard industrial flow equations that will provide the flow rates

the supply pipe is 12", the outlet I'm hoping to use is 3/4", but if its too small, there is a 1" I can use in a slightly less preferable location. full bore valves on them both. Pipe from here to the heater will be about 5 meters, and will need 4 90 degree elbows. The governor can go anywhere, the tendency being to have it near the appliance on almost everything else. I think, at the moment, it will be piped in malleable iron, although it might be copper depending on what we decide if the project is feasible

Thanks for your help

It is worrying that a person involved in the planning of a large volume ( industrial ? ) gas installation is seeking advice from a website for people doing DIY projects.

not really, at such an early stage, and I know there are (or used to be) some very knowledgable engineers on here

You should be able to work out some rough numbers from here https://www.engineeringtoolbox.com/natural-gas-pipe-calculator-d_1042.html

thanks for the link, got it sorted now!

Class wind up...You must have been seriously bored.

so why did you say it was

im not doing any work here, just looking at feasibility. How many kW can I get from a 1" tapping at 70mbar for natural gas. The supply is more than big enough, and again at 3/4"

mbar i said. Mbar would be quite different...
