That's a dumb response.
We need to determine the Bulk Density of solid waste so we can properly design and implement waste collection, storage, and treatment options.
Bulk Density of Solid Wastes play a very important part in the design of landfills, design of garbage collection routes, design of waste composting facilities, etc.
mass/volume=density
Concerning the second Question: "Can you find bulk density with just this info?"Purely on mathematical insight and analysis:Yes, you should be able to find the bulk density of dry soil, given the 'dry overall' and the 'particle' densities.When wet, there is not enough 'given'Also some should be known about the (or your) definition of porosity
You don't
You measure its mass and volume and then density = mass/volume.
First find the bulk density of coal as per the respective grade. then multiply density with volume you will get mass
Bulk density is to find in Wikipedia: http://en.wikipedia.org/wiki/Bulk_density Real density is here to find: http://www.istone.ntua.gr/Training_courses/wp1/real_density.html Apparent density is here to find: http://www.bulk-online.com/Forum/showthread.php?threadid=6440
Bulkdensity is mostly checked to find the capacity of the chemical on how much space it can acquire when its packed.It can be classified as Tapped & Untapped density
on a balance
Solid density is just that - the weight of a fixed volume of the solid material. But if the material is not solid, that is, if it is divided into particles or grains, or "chunks" or the like, then they will not "pack down" and be as dense as a solid volume of the material. Let's try an example. If we have a shoe box full of glass marbles, it will have a given weight. And, if we have the dimensions of the box, we can take the weight and the volume of the box and make a density calculation. But the box won't actually be "solid glass" as it would if we could ignore the "packing" of the spheres. The marbles end up leaving space between and around them when we put them in the box. They're round, and they can't take up all the space in the box. They simply can't. Because they can't take up all the volume in the box, it gives rise to what we call bulk density. If we take the the density of the glass from which the marbles are made, we could find the weight of a volume of that glass that was equal to the volume of the shoe box. The weight of the glass in a shoe box that is "solid glass" will be higher than that of the weight of the marbles in a full box. And that's because it is based on our filling the box with marbles and not being able to make the spaces between the marbles disappear. Got links if you want 'em.
You're pretty much up a creek. You can find the volume using only a ruler, but without a way to find the mass, you will not be able to determine the density.
Any solid that is less dense than water will float in water. This information could be found in a density table. The density of water is 1 g / ml. One example of a solid that floats in water is ice, with a density of 0.92 g / ml.
It is important to study solid waste management because it will, when followed, help greatly in the reduction of wastes brought to dump sites. Thus, lessening the amount of pollution we are bringing to our land. :) Hope this helps!
