For all you math lovers out there...

Which one has more BTU value???

Tank is 400 gallon propane...

The "Boat Rack" is 16' long, x ~58" high...
2 rows of 18" long splits...
Osage Orange...

Let the math begin!!!

This is pretty easy..
A cord of Osage Orange at 20 % moisture is equal to 30.7 million btu's per 128 cubic feet or full cord.
Your pile is 1.812499 cords
So you have 55.6437193 million btu's of wood...if it's dry to 20% if it is drier than you have more btus....and conversely if it is wetter less btu's.

A cord of 20% moisture Osage Orange is worth 337.4 gallons of propane.
You have 611.53716 gallons worth of propane in your pile....roughly speaking that is....so the answer is...your wood has more btus.
 
And Keith get's an A... And extra credit for showing his math...
I like to leave a stack right next to the propane tank...
It's my quiet way of rubbing it in the tank's face...
:hell_boy:
 
Hedgerow can call the gas company to remove that propane tank!

A 400 gallon propane tank holds 320 gallons of propane when full ( 80% )
1 gallon propane yields roughly 95,000 btu's.
320 gallons x 95,000 btu's = 30,400,000 btu's

A 500 gallon propane tank holds 400 gallons of propane when full ( 80% )
1 gallon propane yields roughly 95,000 btu's.
400 gallons x 95,000 btu's = 38,000,000 btu's

1 full cord of firewood = 4' high x 4' wide x 8' long or 128 cubic feet.

1 full cord of Osage Orange produces roughly 32,900,000 btu's per cord.

Based on Hedgerow's stack of Osage Orange:
58" high / 18" / 16' long wide ( x2 )
4.833 x 1.5 x 16 = 116 cubic feet x 2 = 232 cubic feet. ( 1.8125 full cords )
( 256 cubic feet = 2 full cords )

232 cubic feet of Osage Orange = 7,632,800,000 btu's.

What does this all mean?
You will need to fill a 400 gallon propane tank 251 times to = the same btu's as Hedgerow's stack of Osage Orange!
80,320 gallons of propane = 7,630,400,000 btu's
232 cubic feet of Osage Orange = 7,632,800,000 btu's.

I started to agree with you but then your math hit me.
A cord is worth 30.7 million so 1.8125 cords are worth 55.64375 million btus not 7.632 billion btus.

The rest of your math seemed right as in a gallon of propane is worth 91,000 btus...then again they blend propane so it can also have a variance.


I liked your numbers better though in billions instead of millions !!!!!!!

251 fills of a 400 gallon tank or the stack of wood? Here in Michigan we cannot get that kind of btu's out of any wood.... :yoyo:
 
Also if you ever have to fill the tank the driver who delivers the stuff will know why he does not have to come by very often!!!!!
My wood is less BTU's so I have to have a larger pile to = that pile .. but I do not have a Propain tank either. My Nat gas furnace has not run in 3 years!!!

Cutmaster knows Btu's and firewood... And was right on track till he accidentally took the BTU value and multiplied it by the cubic feet as opposed to the cord...
But he still gets a B- because he showed his work!!! I have probably cut close to 232 cord of Hedge in my lifetime, but can't fit it all in the barn all at once...
:sad4:

You may not have Hedge trees, but you have Beech trees!!!
And they're AWESOME!!!
I miss them...
So leave them to grow for a few more years, and concentrate on all them Ash trees up there!!!
I like them too... Unfortunately, so does that damnable bug!!!:msp_mad:

Holy crap that was hard on the brain but very interesting.:msp_smile:

I think what struck me the other day, "And prompted me to take a picture", was the 2 fuel sources sitting side by side... Which had me doing some mental gymnastics on how similar the BTU's were in a given space... If I were to cut the top off that tank, I could fit a similar amount of BTU's worth of Hedge into that tank... That's just a lot of energy in a relatively small dimension...
That, and, I needed a place to put that stupid boat...
:amazed:

billions instead of millions, them huge crappies got my thumb shaking on my zero key!!!!!
CrappieKeith, you gotta show me where fish like that are at!!!:msp_thumbup:
Have boat! Will Travel!!!!!

:sad4:

A B- ?? Man this is all CrappieKeith's fault, it takes 5 of my crappies to = 1 of his!!!!
And I'm not kidding! Look ma, no zeros this time!:blob2:

Hedgerow, that boat is dern fine for shootin Geese and Ducks!

That's what I had in mind, but when the boy and I took it to the river, it leaks, and is too small... Your ass goes numb on the short little benches, and it feels more like a canoe than a boat... I like my bass boat better... And wish I had my saw back... It wasn't even a good saw...
:msp_thumbdn:

:amazed:[/QUOTE]


Hedgerow, PUT THE BOAT on a slow and lazy river . using an 1/8 ounce long shank jig head dressed in a 3"-4" green, mud or silver-gray tube jig tied to a lite-medium weight fishin' rod, 6'-7' long with 6 pound test line and spend yer daze of summer doin' COMBAT with the MAJESTIC SMALL MOUTH BASS !!! :rock:

There is ABSOLUTELY NO BETTER SENSATION on small inland rivers than doin' COMBAT with SMALL MOUTH BASS on light weight fishing gear. (the venerable shimano 2000 reel has enough drag in it that you can fight 'em without losing 'em)


From the looks of yer' wood pile, you should treat yourself to AT LEAST a dozen trips in that boat this summer, I'd say you've earned it. :blob2:
