How much does one gallon of produced salt water weigh?

Answer 1

Weight of a Gallon of Salt WaterSee the web links below this answer for an automatic calculator that will give you the density of water at whatever temperature and salinity you want. Once you know the density, it is easy to figure out how much a gallon weighs ( 1 m3 = 264.17 gallons, and 1 kg = 2.2046 lbs, and 1 gallon = 3.7854 liters)

Here are opinions and answers from FAQ Farmers:

• This depends on the amount of salt dissolved in the water. Sea water in the Atlantic might weigh differently than in the Pacific, and the water in the Dead Sea is much heavier than you might find down at the local beach.

• To get an exact answer, you must know the percent composition of the salt water, or the ratio of salt to water. Roughly, salt water weighs 64 lbs/cu. ft., as opposed to fresh water, which is about 62.2 lbs/cu. ft. There are 7.4805 gallons in a cubic foot. So a gallon of salt water weighs 8.556 lbs.

• "A pint's a pound, the world around." That's a common expression. A pint is 16 fluid ounces and 16 fluid ounces of water weighs approximately 16 dry ounces. Two pints to the quart, four quarts to the gallon means eight pints to the gallon, so a gallon weighs about eight pounds. But that only applies to FRESH water. Salt water has a whole range, depending on how much salt is dissolved in the water. So you'd have to add the weight of the dissolved salt.

Ans 5 - An Imperial Gallon of salt water weighs approximately 10.2 pounds, depending on where it's from. -(seas and oceans vary in density)

Answer 2

Seawater has a density of about 1.025 g/mL (it will be more dense at the deepest depths though). There are about 3785 mL in one gallon, so one gallon of seawater has a mass of

1.025 * 3785 = 3879 grams per gallon

Converting this to weight...

3879 grams per gallon = 8.552 US pounds per gallon

Answer 3

One gallon of salt water typically weighs around 8.6 to 8.8 pounds, depending on the salinity level of the water. The salt content in the water increases its density, causing it to weigh more than fresh water.

Answer 4

To answer this question as best as possible, which I've had to do many time preciously for architects and engineers, I offer the following: Freshwater, assuming it is relatively free of 'too many pollutants' (good luck finding any 'PURE WATER' - since greedy, moneygrubbing industries have polluted about all of it on the planet), is nearly always listed at 8.33 lbs. per gallon. However, according to my 'very accurate scales', a single (U.S.) gallon of 'freshwater' weighs-in at 8.44 lbs. per gallon. Saltwater ('pure saltwater': meaning 'purified- freshwater' with a synthetic seasalt completely mixed to a specific gravity of 1.022 (again, the 'recommended' specific gravity measurement is another argument altogether). However, this mixture (at what 'I' think an 'ideal' 76 degrees Fahrenheit) is much heavier than Freshwater, comming in at 11.(sumthin')lbs per gallon; which is (obviously) approx. 1.5??? lbs per-gallon heavier. And... Even though nobody asked:

There is 231-cubic inches in a standard U.S. gallon. Therefore, to find the 'exact volume' of water in a rectangle shaped container, the following formula will provide the answer:

Multiply the length (inches), times width (inches), times the height (inches) and divide the total by 231. Ta-Da!... One cubic foot of saltwater is approx. 7.5 U.S. gallons and 'true' weight is determined by the 'exact' salinity (and in a miniscule way, the temperature & water purity, as well... Hope this answers your question (and HELPS!) Kindest regards...

Answer 5

The salt water in the Gulf of Mexico is about 2.5 percent salt and has a density of

about 8.47 lbm per gallon.

m = ( d ) ( V )

m = ( 8.47 lbm / gal ) ( 1.0 gal ) = 8.47 lbm <----------

Answer 6

The mass and weight of a gallon of salt water depend upon the temperature

and the salt concentration in the salt water.

Assume that T = 60 F and C sub salt = 5 mass percent

d = ( 64.4 lbm / cu ft ) ( 1.0 cu ft / 7.4805 gal )

d = 8.61 lbm / gal

m = ( d ) ( V )

m = ( 8.61 lbm / gal ) ( 1.0 gal ) = 8.61 lbm <---------------

One gallon of pure water at 60 F would have a mass of 8.34 lbm .

Answer 7

I believe the average weight should be higher than 8.5/gal., as the salt is constantly being diluted, at near surface; by rainfall, and freshwater inlets...

Taking a sample a mile from any land mass and at a depth of 100 feet, should be closer to a true weight....

A GALLON OF SALT WATER WEIGHS 8.556 LBS. A CUBIC YARD OF SALT WATER WEIGHS 1728

Answer 9

I believe it is the amount of a trash can divided by a squirrel then you multiply that by pie.

Answer 10

This depends on the density of the salt water and this depends on the salt concentration.
Mass= volume x density
