Put it in a tank with water. Then total weight of tank + water + stingray, then take out stingray and weigh tank + water. The difference is the weight of the stingray.
The empty weight of a 100 cubic foot steel SCUBA tank is approximately 33lbs.
To calculate the weight of gasoline in a tank, you would need to know the volume of gasoline in the tank and its density. Multiply the volume by the density to get the weight. The density of gasoline can vary depending on factors such as temperature and composition.
The weight distribution is constant because fluids transmit pressure evenly.
For a round tank you must find the volume of the tank - V (cubic ft) = pi x radius squared x the depth or height of the tank. The radius and the depth are in feet. Next take the volume x 7.47 = Gallons of water in the tank The weight of the tank is the weight of the water x 8.4 example: A water tank that is 2 ft. in diameter and has a height of 5 ft. The radius is 1/2 of the diameter. V = 3.1416 x 1 x 5 = 15.708 15.708 x 7.47 = 117.34 117.34 x 8.4 = 986# approx.
6-ft x 2-ft x 1.5-ft = 18 cubic feet. If the tank were 3/4 full, then it would contain 13.5 cubic feet of something. Its weight would be the weight of the tank plus the weight of the contents. We have no way of knowing the weight of the tank. The weight of the contents depends on what substance the tank is 3/4 full of. If water, the weight of the contents is about 842.8 pounds! (rounded)
The empty weight of a 30-pound 410A refrigerant tank typically ranges from 20 to 30 pounds, depending on the manufacturer and design of the tank. This weight refers to the tank itself without any refrigerant inside. Always refer to the specific tank's label or manufacturer's documentation for precise specifications.
a tank is about 1000 pounds on weight
gallons
weigh him, and then find his volume by submerging him in a full tank of water, and measuring the amount of water that has overflowed. Once you have the volume, divide his weight by that, and you will have his density
250 LBS plus the weight of the tank
also the weight of 747 on a full tank
