propane limit 100# tank
- Thread starter HWY36

I would double check the rated capacity versus actual capacity, because 100# capacity is typically based on water and butane has a specific gravity of .601, with propane at .585.
As LPG tanks can only be filled to 80% capacity, that means the 100# tank holds 80# of water, 48 lbs of butane, or 46.8 lbs propane.

GW, This is from their website. The Q and A claims the tank is rated for 100lbs of butane with 80% safe capacity. Does this sound right? I don't want anything to go wrong wrong wrong! THX

i have your 100lb solvent tank. what should the weight be of the tank when filled. what is your guys recommendation for amount of solvent in them.
Our 100lbs solven tanks are rated for 100lbs of N-Butane storage and 80% safe capacity.*
Your 100lb solvent tank is a height of only 19 in? Is that a typo?
Yes, Sorry about that! The height is*55 inches
What are the dimensions? 55" tall X what diameter?
100#/.8= 125#
125#/ (.0361X.601)= 5761 in3
5761 in3 / 55" = 104 in2
Square root of (104 in2/.7854) =11.55" ostensible diameter
Is it that big?
It's just shy of 12 inches (whatever that exactly means) according to the rep.
A 12" dia tank 55" long would hold 100# butane at 80% fill.
It would hold exactly the same amount of propane, but would only weigh 97.3#.
Thank you sir. May I ask how to do the math to arrive at the numbers?
The specific gravity of n-Butane is .601 and n-Propane is .585.
(100#/.601) X .585 = 97.3#
Does anyone know why propane has a specific gravity of .585 and both .495 on the engineers toolbox sight? It's the only gas on there with two different specific gravity.
My guess is they are referring to n-Propane and Cyclopropane, but I show n-Propane with a specific gravity of .495, and Cyclopropane at .68.

My .02, I've been using 100# tanks to heat my shop for the last 6 years. I don't know the math, but from first hand experience they only hold around 23.2-23.5 gals of propane before the safety/overfill valve (whatever its called) starts spraying to maintain safe levels. Hope it helps.
