Natural gas conversion (from MJ/hr to L/s) Urgent!
Natural gas conversion (from MJ/hr to L/s) Urgent!

Hi Robert and ...,
As part of my study, I have to do an experiment on gas pipe bought from a gas pex company which supplies a sizing and test table:
http://www.gaspex.com.au/sizing.htm
I have connected the pipe to a gas-meter then to an air tank. Measure the volume of gas as liter per second (L/s) then compare to the above table which states the value in MJ/hr.
I know you have posted this message:
1 ft³ of natural gas = 1,087,200 joules
and based on that to make a conversion from MJ/hr to L/s to compare to my test result. However, the converted result is different to my tutor note as:
(MJ/hr) *1000/(38*3600) = L/s
(I do not know if his formular is right or not???)
Please give me any idea about that matter and the source where you have the above conversion from. I really need to verify urgently!!!
Many thanks!
GH

The results only differ slightly.
mine: 1 liter = 38417 joules
yours: 1 liter = 38000 joules
Your result is fine, no reason not to used it.
All natural gas is not the same and all energy density reports will differ slightly. I have seen results from 34.6 MJ/m³ to 39 MJ/m³ (34600 to 39000 joules/liter)
Your tutors estimate of 38000 is fine, though the formula is confusing. Would have been better to list it like: (1000/38) / 3600 which separates the MJ to liter conversion factor from the hour to second factor.
