Conversion Help Required
Hi I require some helpful advice and perhaps an example of the formula, for taking British Thermal Units, and then somehow converting them into Kilo Jules.
I hope that is enough information thanx in advance
Sparrow.

Re: Conversion Help Required
Ok I think this is quite difficult, i have found this out for myself thus far.
1x ton = 12000 btu/h = 200btu/min =3517w
The above is approximately the power to cool 1 short ton of water. This is done at 1deg f every ten minutes.
This is the less common usage of power required to cool 1 long ton of water,by 1 deg fevery ten minutes
=13440 btu/h = 3939w
Do i have to convert to watts first? then find kilo joules? can anyone help?

Re: Conversion Help Required
1 kWh equals 3,6 MJ
So that's: 1 kiloWatthour equals 3,600,000 Joules
1 BTU equals 0,29307121 W

Re: Conversion Help Required
Thanks for your help everyone, I have written two pages on the conversion of BTU/H to Watt and KJ I think the answers my tutor is looking for must be in there somewhere,lol

Re: Conversion Help Required
Aha,
You were cheating for a test!
And here we thought that we were giving a fellow engineer advice on a practical problem....
We should have guessed.
(Good luck with your tutor, hopefully he's not on this list)
