Here you go

X.XXX (edit) 7.481 gallons in a cu ft or 1 gallon is 0.1337 cu ft

Not for nothing, maybe a typo

my table says that there are 7.48052 gallons per CF, call it 7.481.

Your 0.1337 (0.13368 by my chart FWIW) is correct, so I suspect a typo inverting the 1 and the 8.

The volume is at 68 degrees by the way, so if you are storing hotter water you may have to correct things, but if you are that close....

You sir are correct

volume at 68F??????????????

a volume is a volume is a volume!!!!

a gallon is a gallon, which is of course is also a cu ft, cu inch , cu meter..etc.... milliliter

now if you are converting gallons to pounds or kilograms that then would be a temperature story.

The volume of water changes

with temperature, JP. More accurately, it is the density but volume and weight are so interdependent that way.

If it did not change, then gravity hot water systems were a major hoax

I see your point in the absolute, but volume is relative to temperature when comparing different substances.

If you filled a cubic foot container made of one material with water at a hotter temperature you would feel short-changed when it cooled. It would be smallest in volume at about 39 degrees F. (4 degrees C.) So one always needs a temperature reference when measuring volumes of anything, gasses, liquids and less affected, solids.

Anyway, my table stipulated the temperature factor, FWIW

word games

of course I agree with density changes vs temp Brad.

but if you read the question without any assumption, then 4.32 gallons of 200F water will have the same cu ft as 4.32 gallons of 33F water. just don't alter the temperature!

kind of a trick question if you disect it

weights, densities and volumes can be tricky when mixing water & alcohol!

Reminds me of the question "What is heavier, a pound of lead or a pound of feathers?" Both measured at 70F of course.

A pound of gold

is measured in Troy Ounces and if you are lucky enough, Troy Pounds. We use the Avoirdupois system for most commercial measurements but Troy is used for precious metals.

A Troy Pound is about 0.83 Avoirdupois Pounds.

There are 12 Troy Ounces in a Troy Pound, so if you are talking about ounces of gold or feathers, all bets are off. A Troy Ounce is about 10% more that an Avdp. Ounce.

No whining now! I told you it was a trick question...

Love it

You are so much better at this than I. Will you write my next rebuttal?

:-))

Thanks, Jack

But trust me, you do not want me to write responses to unreasonable change orders....
