![]() ![]() You can ask a new question or answer this question. ![]() Therefore, the weight of 1 gallon of water is approximately 8.344 pounds. Weight of 1 gallon of water ≈ 8.344 lb/gallon Now multiply the specific weight by the volume: Weight of 1 gallon of water = 62.4 lb/ft^3 x 0.1337 ft^3 Since the specific weight of water is given as 62.4 lb/ft^3 and we know that 1 gallon is equal to 1/7.48 cubic feet, we can substitute these values into the formula: Weight of 1 gallon of water = Specific weight of water x Volume of 1 gallon Now let's calculate the weight of 1 gallon of water: To determine the weight of 1 gallon of water, you can use the specific weight value you provided and the conversion factor between gallons and cubic feet.ġ gallon of water is equivalent to 1/7.48 cubic feet (since there are 7.48 gallons in 1 cubic foot). Therefore, the weight of 1 gallon of water is 62.4 pounds. Weight of 1 gal of water = 62.4 lb/ft^3 * 1 ft^3/gal Now, we can multiply the conversion factor by the specific weight of water to calculate the weight of 1 gallon of water, in pounds: To determine the weight of 1 gallon of water, we can use the given specific weight of water.įirst, let's convert 7.48 gal/ft^3 to ft^3/gal by taking its reciprocal: 1.940 sl/ft 3 32.174 ft/s 2 1.940 lb f/(ft/s 2ft 3) 32.174 ft/s 2 62.4 lb f /ft 3 See more about the difference between mass and weight. Now, that's a weight you can lift without worrying about losing an arm! The density of water is 1.940 sl/ft 3 at 39 ☏ (4 ☌), and the specific weight in Imperial units is. Therefore, one gallon of water weighs about 8.35 pounds. So, if we divide 62.4 by 7.48, we get approximately 8.35 lb/gal. We know that there are 7.48 gallons in 1 cubic foot, and the specific weight of water is 62.4 lb/ft^3. It's that "Oh no, my arm is going to fall off" weight.īut seriously, let's do the math. the exact amount your arm feels like when you try to hold on to just one grocery bag for dear life, but it's full of way too many heavy items. Well, since you're asking for a specific weight, I'm going to have to throw some funny numbers at you. Since g = 32.2 ft/sec² (9.4 answers Take a look at the units you have been given:Ħ2.4 lb/ft^3 * 1 ft^3/7.48gal = 8.34 lb/gal In the U.S., density is often given as pounds per cubic foot, lb/ft³ The specific weight and the fluid density are related by the acceleration due to gravity, or Its units in the English system and the SI system are lb/ft³ and N/m³ or kg/m² It is usually denoted by the Greek letter γ (gamma) and has dimensions of force per unit volume. Specific weight, sometimes referred to as unit weight, is simply the weight of fluid per unit volume. The density of water is 1.94 slug/ft³ or 1000 kg/m³ (1 gr/cm³) It is possible to convert between the English system and the SI system by substituting the equivalent of each dimension with the appropriate value. The units of density in the SI system are kg/m³ or N The units of density in the english system are Slug/ft³ or lb Since the units of acceleration are ft³/sec² F(force) = M(mass) x g(acceleration due to gravity) By using the LFT dimension the slug can be obtained by relating mass to force with acceleration due to gravity. In the Systeme International (SI), the common dimensions are mass, M, length, L, and time, T. Dimensions commonly used in connection with this system are force, F, length, L, and time, T. The old English system of units uses the slug for the unit of mass and feet for the unit of length. The dimensions of density are mass per length cubed or M / L³ Fluid Density is the mass per unit volume and is denoted by the Greek letter ρ (rho). ![]()
