Engineers Argue!

A @jeepinmatt rip off thread. Got a custom built fuel cell in my rig that is....
30" wide x 14" length x 15" deep.
Capacity is?
My CMS math from 1978 sez 26.2 gallons. But i was stoned during that era.
What say ye educated ones?

Gonna need the thickness of material to get an exact number....

1/4" wall. Cuz dats how i roll. Over. Time and time again.

 

[broncosbybart]

My 'engineering' brain says no math needed. Take it to the gas station and fill it up.

I like this thread already.

Fill it with water. Pour the water out into jugs. Count the jugs.

I'm sure you have that many jugs laying around right?

 

[RatLabGuy]

Don't forget about the bit you'll never get off the bottom, or the bit you spill out overt the top

25 gallons even

If you are serious about the 1/4" thick walls and provided exterior dimensions.

@upnover , your new fuel cell is 25 gallons.
Parting out a rig is fun!

I'll be able to handle that!
Bringing it to the toy run? I know you have so much time to spare LOL

I think you meant 27.2, which is what the outside dimensions give you. Calculating the inside dimensions is 25 gallons like @drkelly and @shawn said. Of course they forgot to account for weld bleed into the inside and plate warpage, so it's probably more like 24.987 +/-0.243951 gallons.

Don't forget to account for fuel pump and pickup displacement.

Well it is empty Schlitz Malt Liquor Bull 40s and thats hard to calculate into galions..........

It has a bottom sump

I came up with 94.6353

you are wrong then.
But you didnt state units so 94.6353 Clys could be accurate

Actually, it would be 27.27273, if you are rounding to 1 decimal point, it would be 27.3

He's a conservative. So he always rounds down.

Actually I'm just guessing at @Paul's mistype, so whatev bros.

I consider myself more of a truncater (is that even a word?)
