Advice 1: How to translate tons of solid waste in cubic meters

Enterprises whose duties include the handling of solid waste, use different units of measurement. Management companies, which take out containers with waste from households, usually consider the volume of waste. Landfills and processing plants accept waste most often in tonnes. The company must settle with each other, and therefore to calculate the value of a common unit of measure of solid waste.
How to translate tons of solid waste in cubic meters
You will need
  • - scales for weighing of containers;
  • calculator.
Instruction
1
Please specify what kind of garbage it is. Waste have different densities and, accordingly, the calculations are different factors. If your community adopted the separate collection of solid household waste, find the density of plastic bottles, cardboard, glassware, etc. for Example, the average density of plastic bottles is about 30 to 40 kg/cubic meter, slightly different data for corrugated cardboard and aluminum cans. But a glass density is almost ten times more.
2
The density of ordinary garbage in various conditions will also be different. For example, an unauthorized dump it is 80 kg/cu. m in containers of 180 to 240 kg/cubic meter, and the dump can be even 500 kg/cu. m. Determine at what stage of processing you will have to transfer one unit to other.
3
In some cases it is possible to determine the experimental density of solid waste. Collect containers with the same type of garbage. What will be more, the more accurate will the result. Containers shall be filled according to the standard (i.e. there should be no overfilling, no underfilling). Calculate the total weight of solid waste and divide it by the number of containers. You will get the average weight of garbage in one container. Dividing it by the volume, you'll find the average density. You can get total weight and divide it by the volume of all containers.
4
Remember how to Express the volume of any substance through its mass and density. It can be calculated by the formula V=m/ρ where m is the mass of the material and ρ is its density. By dividing the mass of solid waste for medium or experimental density, you will get the desired volume in cubic meters. Accordingly, if you know the volume and density, multiply them to get the tonnage.
Useful advice
When converted it is better to use the density values given in reference literature. With self-calculation of density of a very easy mistake to make, and it can have far-reaching consequences. For example, built a plant for processing of solid household waste, it suddenly inestor will be unprofitable. Average indicators allow to avoid confusion.

Advice 2 : How to convert ton to yards

Life sometimes poses a non-trivial task. One day my beloved man will ask you: "do you Know how to convert ton to meters?", and you will say, "Sure, you know." It's time to learn this simple manipulation, in order not to lose face.
How to convert ton to yards
You will need
  • 1. the car carrying more than a ton; 2. a ton of fence to build a fence or other household needs; 3. the tape or tape measure; 4. a piece of paper.
Instruction
1
1. Get somewhere a ton of the fence. You can buy or rent in the store building materials for the experiment. Importantly, the weight corresponds exactly to one ton. Submerge the fence in the car and take him to a prepared place where you will be transferring tons to meters.
2
Unload a ton of fence in a small space where you will not be disturbed (for example, at his dacha). Armed with a measuring tape or tape measure, measure the length of each plank, fixing all on a piece of paper. The process is labor intensive, please be patient. It is recommended to put all measured boards in a separate pile, not to confuse them with have not measured the plates.
3
When all the boards will be measured and all data recorded, perform some simple math calculations. Fold the length of all planks to each other. You can use a calculator to perform calculations in a column or count in mind. The result will be the desired value. You moved a lot of fence (in kilograms) length (centimeters).
Useful advice
It is possible that all the boards from tons of fence will be the same length. In this case, the task is simplified - you will need to measure the length of one plank, count the boards and multiply one value by another.

Advice 3 : How to convert from kg to m

The number of tasks you need to know in a piece of material what length is the specified weight. In this task, knowing the pounds, you need to find the meters. This translation requires knowledge of the linear density or ordinary density of the material.
How to convert from kg to m
You will need
  • the linear density or the density of the material
Instruction
1
Units of mass are converted to units of length by using a physical quantity called linear density. In the SI system it has the dimension of kg/m. This value differs from the usual density that expresses the mass per unit volume.

Linear density is used to characterize the thickness of threads, wires, fabrics, etc., as well as for the characterization of beams, rails, etc.
2
From the definition of linear density, it follows that for the translation of the mass in the length needed to divide the weight in kilograms per linear density in kg/m this gives you the length in meters. This length will contain this mass.
3
In that case, if you are aware of the normal density with the dimension kg per cubic meter, to calculate the length of the material, which contains weight, you must first obtain a volume of material, encompassing the mass. To do this, divide the mass by the density. Then, the resulting amount is divided by the cross sectional area of the material. Thus, the formula for the length would be: l = V/S = (m/p*S) where m is the mass and V is the volume containing the mass, S is the cross - sectional area, p is the density.
4
In trivial cases, the cross section of the material will have either a round or rectangular shape. The area of the circular section is equal to pi*(R^2), where R is the radius of the cross section.

In the case of rectangular cross section, its area is equal to a*b, where a and b are the lengths of the sides of the section.

If the cross section has an irregular shape, then you need to find the area of the geometric shape in cross-section.

Advice 4 : How to convert kg to cubic meters

At the decision of physical tasks is often required to translate physical quantities from one system of measure to another. As a rule, this process does not cause special difficulties. Units of homogeneous physical quantities are linked through their respective coefficients (occasionally, simple formulas). However, in practice, sometimes you have to work with heterogeneous values and translate, for example, kilograms per cubic meter
How to convert kg to cubic meters
You will need
  • calculator
Instruction
1
To convert a known amount of kg per cubic meter, find the density of a substance to which he is transferred. To do this, locate the appropriate table of the density of a substance. For convenience of calculations the density of the substances in this table should be indicated in kilograms per cubic meter (kg/m3). This is the standard unit of density in the SI (system international).
2
Defining the table the matter density, use the following formula:
KMK = Kkg / P,

where: KMK – the number of cubic meters,

Kkg – number kg (kilograms),

P – density of the substance expressed in kg/m3.
For example, suppose you want to calculate what volume (how many cubic meters is 10 tons (10,000 kg) of decking.
Solution:
Find (online) the density of the decking. It is 800 kg/m3. Using the above formula, we can calculate that the number of cubic meters will be:

10000 / 800 = 12,5
3
It often happens that to determine the density of the substance in the tables difficult. For example, some tables may not be at hand or don't know the name of the substance. Sometimes items can be constructed from several materials, combined in unknown proportions. Moreover, even the known density of the substance (material) can vary within wide limits (for example, the density of wood depends on its moisture content).
4
If you define the density of matter in the following table, measure it yourself. For this (possible) separate a piece of material, preferably of regular shape and calculate its volume in cubic meters. For example, if boards, then sawed off smoothly about half-meter segment of the Board. Then measure (in meters) the length, width and thickness of the sample. Multiply these numbers – the resulting work would amount. Now weigh the scrap Board and divide his weight (in kg) to the previously calculated volume (m3). The resulting number will be equal to the density of the Board in kg/m3.
5
If the cubic meters it is necessary to translate a known amount of a kilogram of water or weak solutions of other substances, the liquid density can be taken equal to 1000 kg/m3. This density value can be used in the rough (estimated) calculations of the volumes of other liquids.
To get an accurate value of the density of the liquid, pour the liquid in a measuring cylinder or fill her a container of known volume. Then weigh the liquid container and divide its mass (excluding the weight of packaging) per volume. Follow the same procedure to obtain the density of bulk materials.

Advice 5 : How to convert to tonnes cubic meter of sand

The most commonly used measures of matter are volume and mass. The volume of the components, widely used in manufacturing and construction, such as sand, is usually measured in cubic meters. This measure, in common parlance, called CC, based on the mass of available sand, you can always find its volume or, put differently, the number of cubes.
How to convert to tonnes cubic meter of sand
You will need
  • - the density of the sand.
Instruction
1
First define the density of the sand. The relationship of mass and volume of a material is expressed through the figure. Each substance has its own density and it is constant. This characteristic is measured in kilograms per cubic meter. To define it, using physical directory, which contains the relevant tables. The density of the natural sand is 1,300 kg/m3. Worth noting that along with the humidity increases the density of the sand will also increase. For calculations take the following values: the density of wet sand 1500 kg/m3, the density of wet sand with admixtures of clay 1800 kg/m3.
2
Calculate the mass of sand. The formula connecting the volume and weight is as follows:
m = V∙R,
where m – mass; V – volume; R - the density.
As can be seen from the above relation, in order to find the mass of matter, knowing its volume, multiply the value of this volume by the density of the substance. The magnitude of V is known number of cubes.
3
Translate the obtained value of the mass from kilograms to tonnes. The table value of the density has the dimension kg/m3. Accordingly, the estimated value will display the mass of sand in kilograms. In order to convert this value to tons, you must know that 1 ton is 1000 kg. Thus, the obtained in the course of calculations, the number should be divided by 1000. The result – the available mass of sand, expressed in tonnes.
4
Let's consider an example. Let there be 12 cubic meters of wet sand. Determine its mass.
1. The density of wet sand R = 1500 kg/m3.
2. The volume of sand V = 12 m3. Its mass is m = 12*1500 = 18000 kg.
3. 18000 kg = 18000/1000 = 18 tons.
