### Calculation of glass thickness for aquarium: a table that can help

Each type of fish has its own preferences for size. aquarium. Someone needs a lot of space, and some kind of can be content with a small amount of water.

Therefore, it is important to be able to calculate the volume aquarium, to grow healthy pets. The question “opened a pet store. Business is not going. What to do? “- 2 answers

1. You can calculate the geometric and actual volume aquarium. Geometric volume is the amount of water that will fit in an empty aquarium. It is calculated by the formula a * b * c, where a is the length aquarium, b is the width and c is the height.

But in fact, in addition to water, in the existing aquarium you will have soil, shells, perhaps a decorative sunken ship or an underwater castle, equipment necessary for fish life, algae and the inhabitants themselves. 2. In order to calculate the actual volume aquarium, the safest thing would be to use measuring dishes or even a regular can. Pour soil and shells into the future dwelling, install necessary equipment, put decorations on it and start filling the tank with water with the help of a container, not forgetting to count how many times you scooped water.

Once the tank is full, multiply the number of liters that fit in the dishes by the number of times you had to fill it with water. As a result, you get the actual amount. Of course, in this case it is more convenient to calculate the volume immediately before the fish is settled, although this is a good way to check the tightness of the aquarium.

The same method can be applied to round aquariums, since it is impossible to calculate mathematically their volume exactly. 3. Often, the manufacturer writes on the aquarium its volume. The most common measurement unit is liters, cubic centimeters and cubic meters.

Remember that one liter equals one cubic decimeter. If you bought an aquarium in England or America, its capacity can be measured in pints or inches cubic. One pint will be equal to 0.57 liters.

If you are dealing with an American pint, the value will be different – 0.47. One cubic inch is 0.016 liters. ## How to calculate the volume in liters :: how to calculate the number of liters in the tank :: Natural Sciences

Any liquid container, such as a can or water bottle, has a certain amount that is measured in liters. However, there are cases when the volume is known in cubic meters.

In this case, you need to be able to translate meters into liters. The question “And yet! What appeared first? Egg or chicken? “- 12 answers

1. There are several ways to calculate volume in liters. If you encounter a liquid that is packaged in a bottle, then there is always this volume indicated in liters. However, there are containers on which the volume is indicated in cubic meters.

From primary school it is known that in 1 m ^ 3 = 1000 l. Accordingly, if you need to find the volume of any capacity in liters, you must multiply the specified value in cubic meters by 1/1000: a (l) = b (m ^ 3) * 0.001. Thus, you can calculate the volume in liters for a given volume, measured in m ^ 3. This is a simple translation from one SI unit of measurement to another.

However, if you do not yet know the volume, you will need to first find it in meters, and then translate into liters.

2. Suppose you know only the mass of the liquid in the container. With the help of a simple formula, which is known from the school physics course, one can find the volume. The formula itself looks like this: p = m / V, where m is the mass of the liquid, p is the density of the liquid. You can find the density of the liquid based on the tabular data.

In all physics textbooks, the densities of liquids are given, including water, oil, kerosene, mercury, etc. Accordingly, the volume is equal to: V = m / p (m ^ 3). Further, also according to the scheme, V (l) = V (m ^ 3) * 0.001.

3. If you know neither volume nor tare mass, but it is a clear stereometric figure, for example, a cylinder, the volume can be found in two stages: first you need to carry out experimental measurements, and then – algebraic calculations. To do this, you need to measure the radius of the base of the cylindrical container and its height.

The volume of such a container will be equal to: V = πR ^ 2 * H, where R is the radius of the base of the container, H is the height (m ^ 3). Similarly, V (l) = V (m ^ 3) * 0.001.

## How to calculate the volume in liters :: volume converted to liters :: Math

To calculate the volume of a body or substance in liters, you need to know its volume, expressed in other units. If the volume of the body is not known in advance, then it can be calculated in terms of mass and density.

There are special methods and tools for measuring mass and density. The question “How to determine the volume of the pipe? If its length is 200m and the diameter is 65mm.” – 3 answers

1. If the volume is specified in cubic decimeters (dm³), then the volume in liters expressed by the same number. Therefore, simply change the unit dm³ per liter (l).
Vl = Vdm³To convert to liters of volume specified in cubic meters (m³), multiply the specified numerical value by 1000.
Vl = Vm³ * 1000To convert to liters the volume specified in centimeters cubic (cm³) or milliliters (ml), divide the given numeric value by 1000.
Vl = Vcm³ / 1000 = Vml / 1000. To calculate the volume in liters, if it is set to the deckliters (long) or buckets, multiply the number of decalitres by 10:
Vl = Vdl * 10

2. If the volume is given in non-metric units of measurement (national or household), use the following instruction: If the unit of measurement of a known volume is an American gallon, then to calculate the volume in liters, multiply it by 3,7854. Do the same with other units of volume: American Quart – multiply by 0.9464;
US gallon – 3.7854;
American dry barrel – 115.6270;
American Bushel – 35.2391;
American liquid barrel – 119,2400;
oil barrel – 158.9873;
Imperial gallon – 4.5461;
Imperial Quart – 1.1365;
Imperial Pint – 0.5683;
Imperial ounce – 0.0284;
American pint – 0.4732;
US ounce – 0.0296;
imperial bushel – 36.3687;
teaspoon – 0.005;
tablespoon – 0.0148;
a mug – 1.23 (conditionally);
cup – 0,2;
cubic inch – 0,0164;
cubic feet – 28,3168.

3. If the volume of the body or fluid is unknown, then calculate it using the following formula:
V = m * p, where:
V is the desired volume
m is the mass of the body, fluid or substance
p is its density. If the body weight is unknown, then determine it by weighing. Find the density of the substance in the density tables.
The resulting volume will be in liters, if the mass is given in grams (g) and the density is in grams per liter (g / l). In other cases, recalculate the volume in liters, using the above instructions.

Note that the density of water is 1000 g / l or 1 kg / l or 0.001 t / l. Therefore, to calculate the known mass of water in liters, simply:
weight in grams divided by 1000;
multiply the mass in tons by 1000;
weight of water in kilograms take equal to the volume in liters.

## How to find the volume of a liquid :: water glass nanty :: Math

Liquid is an aggregate state of a substance, being in which it can change its shape without changing the volume. If you pour water from a glass into a jar, the shape of the water will take the contour of the last vessel, but it will not become more or less.

Determine the volume liquids can be a few simple ways. The question “How to determine the volume of the pipe? If its length is 200m and the diameter is 65mm.” – 3 answers

1. To calculate the physical method for finding the volume of any body that is in any aggregate state, knowing its mass and density. That is, if the density is known liquids (for this, it is enough to know its name and further, to find the density table in the physical reference book) and its mass, then simply divide the mass value by the density value. The units of measurement of these quantities should be: if the mass is given in kilograms, then the density should be in cubic meters, if the mass is measured in grams, then the density is in cubic centimeters. Example1: Let it be necessary to find a volume of 2 kg of water.

Solution: The volume is equal to the ratio of the mass (2 kg) to the density of water (it is equal to 1000 kg / (m) cubed). Total volume is equal to 0.002 cubic meters.

2. Another mathematical way to measure volume liquids: in its form. After all, as a rule, it is always poured into any vessel.

Then you need to know how to find the volume of the geometric shape that the piece has. For example, if water is poured into an aquarium, and it is a parallelepiped, then its volume, and hence the volume of water, can be calculated as the product of the height, length, and width of the aquarium. You can do the same with any form.

The basic rule for finding the volume: this is the product of the height of the base area. Example 2: Water is poured to the edges of the aquarium, what is its volume if the dimensions of the aquarium are: 20 cm, 30 cm, 40 cm. Decision.

To find the volume of water, it is necessary to determine the volume of dishes: the volume is equal to the product of the height, length and width of the vessel. V = 20cm * 30cm * 40cm = 240000 cubic centimeters.

Answer: the volume of water is equal to 240,000 cubic centimeters.

3. The easiest way to measure volume liquids measuring vessel having a scale, the price of division, unit of measurement. An example of a measuring vessel could be a beaker, syringe, bucket, glass, etc.

The main thing in this way is not to be mistaken with the readings of the measuring device. Example 3. The glass is half filled with water. It is necessary to find its volume.

Solution: if 200 milliliters of water are placed in a glass as much as possible, then in a half glass – one hundred milliliters.

Volume is the space occupied by the body. It is easy to calculate the volume of the correct object, which can easily determine the parameters (length, width, height). It is only necessary to multiply the values ​​found.

Determining the volume of an arbitrary shape is much more difficult. The question “How to determine the volume of the pipe? If its length is 200m and the diameter is 65mm.” – 3 answers

1. A method for measuring the volume of an object with the help of water was discovered by the Greek scientist Archimedes. To determine the volume of any body, you must take a container with a liquid, it is better if the container is transparent.

The vessel should be applied scale division and measure the volume occupied by water. After that, you need to immerse the body in the water, the volume of which you want to know.

As soon as the water rises, you need to mark a new level. The difference in the levels obtained as a result of measurements will be equal to the volume of the immersed body.

2. In addition, you can determine the volume of the object by measuring the amount of water displaced by it. To do this, in a vessel filled to the top with water, it is necessary to immerse the body.

At the same time, the water displaced by him must be poured into another container and the volume should be measured, which will be equal to the body volume being sought.

3. When finding the volume of a hollow body, you can also use water. To do this, you need to fill it with an existing object, and then pour water into a glass, on which the scale of division is applied.

The measured volume of the body will be equal to the volume of water contained in it.

4. You can calculate the volume of any body, knowing its density and mass. To do this, it is necessary to divide the mass of the existing object by its density.

You can find out the density of a substance from which one or another object is made from the reference tables “Density of solids”

5. For the calculation of some figures derived mathematical formulas. For example, to find the volume of a cylinder, you need to know its radius and height.

The volume of the cylinder you get by multiplying the number “Pi” by the square of the radius and height of the body (V = π * R2 * H). x
