How many square meters will a bulk bag cover?
It depends upon the volume of the bulk bag and how deep you want it covered. Divide the cubic meters in the bulk bag by the depth in meters to get your answer. For example, a bulk bag of 2 cubic meters will cover to a depth of 1 cm. 2 cubic meters / 0.01 meters depth = 200 square meters.
How many pounds of sand to fill a 7' x 8' x 12 sandbox?
It depends on the density of the sand. Certainly, you are talking about 56 cubic feet, but you will need to know the bulk density of sand to figure out how much that weighs.
How does the density of a crushed metal can compare to the density of the metal can before it was crushed?
The crushed can will have a density that is quite a bit higher than the density of the can before it was crushed. Imagine a box of empty aluminum beverage cans. It won't weigh much. If those same cans are crushed, they will weigh the same, but take up a lot less space. The density of the cans can be increased by crushing them. The cans might be said to have a low bulk density before being crushed.
What are equations which can be used to determine the speed of a wave?
The velocity of pressure and shear waves through a solid is dependent on the elastic properties and density of the material through which the wave is travelling.The pressure wave velocity (VP) can be found using the following:VP = Sqrt((K+ (4/3 x G)) /P)Where:K = Bulk modulusG = Shear modulusP = DensityThe shear wave velocity is given by the following:VS = Sqrt (G/P)Where:VS = Shear wave velocityG = Shear modulusP = Density
Is 5 gm cornflour equal to 5 ml cornflour?
No. Corn Flour has a bulk density of 0.82 g/ml which means that 5g of corn flour is 6.1 ml and 5 ml is 4.1g.
