Common Shape Fish Tank Capacity Calculation Method:
1.Volume Unit:
A liter (L) is an international standard unit of volumetric measurement, where one liter is equal to one thousandth of a cubic meter. If we use centimeters (cm) as the unit of length, the volume of the ordinary square aquarium = length, width and height 1000, while the cylindrical aquarium volume = radius radius water level height, the result is the number of liters of the aquarium. Generally, one liter of fresh water weighs about 1 kilogram, and seawater is slightly heavier, but a rough calculation can also be counted as 1 kilogram.
In drug use we usually use smaller units of volume - milliliters (ml), where 1 milliliter is equal to one thousandth of a liter. There is also a rough calculation: about 18 drops of water that drip naturally is 1 ml, which means that 18 drops of medicine into the fish tank is about 1 ml.
Other imported drugs and equipment also use units from the exporting country, commonly gallons and ounces. There are two types of gallons, including the imperial system and the American system, the imperial system 1 gallon is equal to liters, and the US system 1 gallon is equal to liters, and the difference should be noted. The ounce is actually not a unit of volume, but a unit of weight, 1 ounce is about equal to a gram, and some manufacturers like to use it as a unit of measurement for medicines.
2.Concentration Unit:
Many fish farming reference books will use the concentration unit ppm as the concentration measurement of the drug, and ppm is the English part
The abbreviation of permillion, which means:
...... parts per million"Let's talk about the concept of milligram (mg) first, 1 milligram is equal to one thousandth of a gram. 1 ppm is equivalent to the concentration of 1 milligram of the drug added to one liter of water, i.e. 1 ppm = 1 milligram liter, and so on, adding 100 milligrams of the drug to 100 liters of water is 1 ppm.
3.Pump Units:
When buying a water pump, there is often such a problem, that is, how big to buy a water pump. Generally, the manufacturer of the pump will indicate the flow rate and head of the pump in the label on the pump, and the unit of flow is liters per hour (l h or l hr), which is the displacement of the pump per hour; The symbol of the head is hmax, and the unit is meters (m), that is, the maximum height that the pump can lift the water, and it should be noted that this height is calculated from the surface of the water source, not from the outlet of the pump. If the pump is used to create a circulating water flow or drive a filter other than the trickle and upper type, then generally only the flow rate needs to be considered; If you want to drive the above two filters, you also need to consider the head of the pump, because the water flow rate decreases according to the height of the water being lifted.

If it is water, because 1L = 1000UML; And 1ml of water is 1 gram, so 1L of water is 1000 grams, which is 1 kilogram, that is, 2 catties.
There is also a kind of folk "liter" as the unit of measurement.
One liter is one-tenth of a bucket, and one liter of rice is 4,000 grams, which is 8 catties (16 taels = 1 catty). In the past, people did not have standard weights and measures.
On the basis of stupidity, he invented this method of measuring rice by capacity, which is still very useful.
Unit Conversion1l = 1000ml 1000ml = 1000 cubic centimeters.
1 cubic decimeter.
1 ml = 1 cissy (cc).
1 ml of liquid water = 1 cubic centimeter of liquid water.
1 ml of liquid water at 4 degrees Celsius.
The weight is 1 gram.
1 ml = 1 cubic centimeter.

To find how many cubes of water in a water tank is to calculate the volume of the water tank, if the tank is a cuboid, its volume = length, width and height. If the pitcher is a cylinder, its volume = bottom area is high.
If it is irregular in shape and the volume is not very large, fill the jug with water, and then use the container to measure the volume of water, which is the volume of the container.
How to use: measure the length, width and height of the rectangular tank from the inside of the tank, and then calculate the volume of the cuboid according to the formula of the volume of the cuboid Length, width and height, letter formula: V=ABH, because 1 cubic meter of water is 1 ton, so, calculate how many cubic meters of volume, that is, how many tons of water can be loaded.
Secondary water supply. 1. With the development of secondary water supply pressurization technology, the water supply equipment fundamentally solves the problem of water supply from water towers. According to the data of the "Water Supply Equipment Promotion Center", the water supply equipment does not need to build a water tower, the investment is small, the land is small, the use of water and gas automatic regulation, automatic operation, energy saving and tap water automatic grid-connected, power can still be supplied after a power outage, and there is no need to take care of it for several years after commissioning.
2. It saves 70% of investment compared with the construction of water towers and 60% of investment compared with the construction of high-level water tanks, which greatly saves civil engineering investment.
3. Water supply equipment is widely used in production, living and office water in enterprises and institutions, residential areas and rural areas. The number of water supply households is 20,2000. The daily water supply is 20,5000 m3 and the water supply height is up to 150 meters, i.e. 50 floors.

Calculating the volume of a bottle of water requires measuring its length, width, and height, followed by a volume calculation. The specific steps are as follows:
1.Use a tool such as a tape measure or ruler to measure the length (L), width (W), and height (H) of the bottle in centimeters.
2.Formula for calculating volume: Mengxi uses the following formula to calculate the volume v of the bottle in cubic centimeters (cm).
v = l × w × h
3.Convert results to other common units: If you need to convert results to other common units, you can use the following conversion relationships:
1 liter (L) = 1000 milliliters (ml).
1 milliliter (ml) = 1 cubic centimeter (cm).
For example, if the length, width and height of a bottle of water are 10cm, 5cm and 20cm, respectively, the volume of the bottle is:
v = l × w × h
10 cm × 5 cm × 20 cm
1000 cm³
Therefore, the capacity of this bottle is 1000 ml or 1 liter.

The formula for calculating the volume of water is v=m. Volume, a geometric term.
When the space occupied by an object is three-dimensional, the size of the space occupied is called the volume of the object. The International System of Units (SI) is cubic meters. One-dimensional objects (e.g., lines) and two-dimensional objects (e.g., squares) are zero-volume.
Water, with the chemical formula HO, is an inorganic substance composed of two elements, hydrogen and oxygen, which is non-toxic and drinkable. At room temperature and pressure, it is a colorless and odorless transparent jujube annihilation liquid, which is known as the source of human life. Water is one of the most common substances on the earth, an important resource for the survival of all life, including inorganic chemistry, and the most important component of living organisms.

Go home and turn on the faucet for one minute, calculate the water velocity, measure the diameter (or radius) of the faucet, estimate the time of water use, and use the formula "Calculate the drainage = diameter of the faucet * water flow speed * number of faucets * time" to calculate.
For example: the diameter of the faucet is meters, 20 faucets, the water flow speed is 3 meters per second, and the time is 20 seconds, then the discharge = cubic meters.
-
The general calculation method is: water consumption = water consumption, water consumption, the number of units of actual water consumption (also often said: quota quantity).
Water consumption refers to the amount of water used by water users, usually provided by water supply units, or can be obtained directly by water users from rivers, lakes, reservoirs (ponds) or underground water.
Water useThe water consumption of industrial production includes the water used for primary production, auxiliary production and auxiliary production.
In 2020, China's national water-saving action was vigorously promoted, the national water quota system was basically completed, and the total annual water consumption of the country was maintained at about 610 billion cubic meters. In 2020, the third batch of 350 counties and districts will be completed to meet the standards of water-saving society, and 1,790 water-saving institutions and 298 water-saving colleges and universities will be built.
