Volume = 10 ft3 (given) Density = 0.4 pounds per ft3 Specific gravity = about 0.0064 (using 62.5 pounds per ft3 for water)
The specific gravity is a dimensionless term which is the relationship of the density to the density of water. For metric measurements, the density in gm/cc or kg/l is the same because water's density is 1 gm/cc or 1 kg/l (at 3.98 °C, 1 ATM). This would not be true in pounds, gallons, and etc, although if the specific gravity is calculated, then the units will cancel out and the results will be the same.
Specific gravity is not measured in pounds. It is a dimensionless quantity, which results by dividing (in this case) the density of aliminium, by the density of a reference substance, usually water. The result of the division will be the same, whether you use international units (SI, i.e. metric), or obsolete units.
Never. The specific gravity of a substance is its density compared to water. If that happens to be 2.509, then any amount of the substance weighs 2.509 times as much as an equal amount of water. One cubic foot of water weighs about 62.4 pounds, so one cubic foot of the substance you've described weighs about 156.6 pounds. "50 pounds per cubic foot" means that the specific gravity is about 0.80 .
start with known values Specific gravity = 1.0 for water weight = 100 pounds 100pounds/8.36 pounds per gallon = 11.96 gallons ------------------------------------ Specific gravity = 1.5 for unknown liquid weight = 100 pounds 100pounds/ (8.36 pounds per gallon of water * 1.5) = 7.97 gallons At least that's how I wuold do it....
The weight of a barrel of oil will depend on its density. A barrel contains 42 gallons and density is typically measured in units of API gravity. Units can be a bit confusing in this case. We need to convert from API density to pounds per gallon. Crude oil can typically vary from 15 to 45 deg API although I have worked with oils as low as 8 and as high as 50. Let us consider oil gravity of 30 deg API, as all other densities are calculated in the same way. Specific Gravity = 141.5/(131.5 + 30) = 0.876 The specific gravity is the density of the oil relative to water. Now, to convert this to pounds per gallon, we must multiply the answer by 8.34 (density of water is 8.33 pounds per gallon): 8.34 x 0.876 = 7.30 pounds/gallon. Since there are 42 gallons in a barrel, we must multiply this answer by 42: 42 x 7.30 = 307 pounds. To summarize, a) convert API to specific density b) convert specific density to pounds per gallon and c) multiply gallons in one barrel by the pounds per gallon.
specific gravity means that the ratio between the density of pure water to the density of that material is ----- so the density of the water you are talking about is 1.0254966times the density of pure water which is one so the density of that type of water is 1.0254966 density = mass / volume 1.0254966 = mass / 28316.8 mass = 29038.78 gm = 29.038 kg the weight = m g = mass * 9.8 =284.58 N
Specific Gravity is unitless. To determine the specific gravity of something you take the density of the substance divided by the density of water (assuming both densities are in the same units ie: g/cm^3, or lb/in^3So for platinum, whose density is 21.45grams/cm^3 you would take (21.45g/cm^3)/(1g/cm^3(this is the density of water)), so specific gravity=21.45This would be the same answer is you had your densities in terms of lbs.
It is easiest to answer this question using the metric system. 148.5 pounds = 67.36 kilograms So density = 67.36 / 30.5 kg per cm3 = 2.208 kg per cm3 = 2208 grams per cm3 Density of water = 1 gram per cm3 So specific gravity of the mass = density of the mass / density of water = 2208
This question cannot be answered because pounds are units of mass and gallons are units of volume. The mass of 486 gallons would depend on the density or specific gravity of the substance with that volume.
