Only8 Kgs to start with!!

 

Thats not right htough, its only the moisture that has changed in weight not the wood. So with the calc above the 2.75kg is the reduction in weight then taken away from the original to leave 5.25kgs

 

Oh you edited already! Correct 8000g.

 

surely the reduction in weight is the 5.25kg:confused1:

 

but now i am thinking about the logs weight????

 

not sure now

[Rupe]

NO the 5.25 is the new weight, the reuction in weight was the amount you said. But it was still wrong.

[Dean Lofthouse]

The calculation is like workingout vat in reverse isn't it ?

Thanks guys I was sure that was the way it worked but just wanted some clarification. My customer has stipulated that all bags must be above a certain weight and just wanted to make sure that I put enough wood into the nets.

 

 

Thanks again for your help.

I've got brain ache

 

Me too. I can see what I mean but I can't write it! Its like back workign VAT, you don't use 15% you need another mumber.

 

If I weigh 100 kgs and I'm 20% fat. My fat weighs 20kgs. if my fat content goes down to 10% thats a 10% reduction in fat content but not necessarily 10kgs loss in total weight, its not that simple.

 

so it doesn't mean I know weigh 90kgs, because 10kgs (my remaining fat) is NOT 10% (my new fat content) of 90kgs!!!!

[Rupe]

YOu keep beatign me to it dean! Yes your correct.

 

Paper rusrtler, just put logs in the net and don't worry about % stuff, you made my brain acknwoledge its own extistance and thats bad!!

The original post says 8kg at 32% moisture therefore just under 1/3 is water. If this is the case and you dried it completely then you would have 5.44kg of wood left at 0% moisture. The add your 11% of 5.44kg and you get 6.03kg.

 

There is another number to add to the mix......

 

As Dean says it depends on your definition of moisture content. Is 4kg of dry wood 100% wet if you weighed it at 8kg when fresh cut? No, because 100% wet is pure water.

 

Eucalyptus can hold more than its own weight in water (i.e 8kg of euc could be dried to less than 4kg of dry wood), this would mean using Deans method then it is more than 100% wet when freshly cut.

You can have wood with 200 % moisture content

you dont want that customer mate, there is your answer, he will weigh every log and give you know end of grief, pass him onto one of your competition and let them get all the hassle. because that nut case already knows the answer because he has no common sense and nothing else to do except call you up on a sunday morning at 6am to give you another reason why he isnt going to pay you:thumbdown:
