The water volume algorithm of the fish tank, what is the formula for calculating the water volume of

Look at the shape of the fish tank, with different volume formulas, if it is a cuboid or a cube, it is the bottom area multiplied by the height: the length and width of the bottom surface are a, b, and the height of the water is h, then: the amount of water = a b h

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 use the unit of concentration ppm, which is an abbreviation of part per million, which means "parts per million...... for the concentration of drugs"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.

<> water capacity of the fish tank = length * width digging rise * height (single scattered coarse position: decimeters.)

Litre. or length*width*height (unit: cm) 1000 = liters.

For example, a fish tank is 100 cm long * 50 cm wide * 60 cm high.

Fish tank water flushing capacity = 10 * 5 * 6 = 300 liters of water.

or 100 * 50 * 60 1000 = 300 liters of water.

<> fish tank water capacity = length * width Qingji * height (unit: decimeters) = liters.

or length * width * height (in centimeters) 1000 = liters.

For example, the fish tank is 100 centimeters long, and the stove is 50 centimeters wide * 60 centimeters high.

Fish tank capacity = 10 * 5 * 6 = 300 liters of water.

or 100 * 50 * 60 1000 = 300 liters of water.

Hello! First of all, you need to know what size the fish tank is, it is generally calculated in meters, and the calculation method of the fish tank in the shape of different banquets is also different, please refer to the actual situation!

The calculation is as follows:

Square (rectangular): length, width, height 1000

Cylindrical: Radius Radius Pi Height 1000 Precautions: The special-shaped fish tank can be roughly estimated according to the above way, and the thickness of the glass is generally not removed, and the height is subject to the height of the water bend family.

For example, a 120*50*60 cm fish tank is equal to 360 liters of water.

The formula for calculating the water volume of the fish tank is: water volume (l) = fish tank length (cm) fish tank width (cm) water level height (cm) 1000.

If the dimensions of an aquarium are: 60cm, 30cm, 40cm, it means 60 cm long, 30 cm wide and 40 cm high. Simply multiply the length of the aquarium by the width to get the water surface area in square centimeters, for example:

60 cm 30 cm 1800 square centimeters.

Multiply the water surface area by the height to get the volume in cubic centimeters, such as 1,800 square centimeters 40 centimeters and 72,000 cubic centimeters. Divide the calculation by 1000 to convert the volume unit from "cubic centimeter" to "liter": 72000 1000 72, so the water surface area of this fish tank is 1800 square centimeters and the volume is 72 liters.

What are the precautions for fish farming:

1. Into the tank: disinfect with water, not sloppy.

When we buy fish, JS will explain that "when we go back, put the bag in the fish tank first, and wait for the temperature to be the same, and then put the fish into the tank", in fact, this is not enough, we also need to mix water and disinfect.

To soak the plastic bag containing the fish in the fish tank for 10 to 20 minutes before opening it, use a basin to put the fish in it, put 1/1000 potassium permanganate, and use a suction pipe to pump the water from the tank into the tank 3 4 times, with an interval of 5 10 minutes each time. This way it won't affect your newly bought fish too much.

2. The bait must be clean.

This is the most likely to be overlooked by newcomers. Feeding unclean bait can easily lead to fish diseases. It is recommended to buy branded frozen fresh food produced by a professional company, such as blood bloodworms, harvest shrimp, etc.

Although live insects such as earthworms and water bloodworms are the favorite of tropical fish, live insects grow in polluted water environment, and they are very easy to die and decay in temporary rearing, so it is necessary to be cautious when putting live food. It should also be noted that the impurities and residual bait at the bottom of the tank are not cleaned up in time or the filtration effect is poor, resulting in water quality corruption.

The water capacity of the fish tank is calculated as follows:

The easiest way to calculate the water in a fish tank is to measure the length and width of the fish tank, calculate the area of the bottom of the tank, and then multiply it by the water depth, so that the data is more accurate. Water in the fish tank.

The total amount and the volume of the tank are not exactly equal, because the water in the tank is usually not filled, and it is better to reserve about 5 cm.

Too much water in the fish tank will increase the pressure on the fish tank, which can easily cause it to burst. For example, a fish tank that is one meter long, half a meter wide, and half a meter high. Then converted to centimeters, one meter is equal to 100 centimeters, and half a meter is equal to 50 centimeters.

The result should be 100 50 50 = 250000!

Then divide the resulting value by 1000, that is, use 250000 1000 = 250, and finally the number that can be obtained is the liter of water in the fish tank. That is to say, this fish tank is filled with 250 liters of water, and one liter of water is equal to two catties, so this fish tank can hold 500 catties of water!

Summary. The analysis is as follows:

1. First of all, according to the size of the fish tank length * width * height [unit: decimeters], for example: 100 cm length * 40 cm width * 60 cm height, the formula: 10 * 4 * 6 = 240 [liters], the product obtained is the water capacity of the fish tank [unit: liters];

2. The water pump adapts to the flow rate of 3 times or 5 times of the water capacity, generally 5 times is more appropriate, the formula: 240 * 3 = 720 or 240 * 5 = 1200 [unit: l h, liter hour] The amount of water filtered per hour can be purchased according to the water capacity filtered per hour;

3. The following information is for reference: 1800L H, about suitable for 11W variable frequency submersible pump. Or a 30W general water pump.

4. If you buy a submersible pump in **, the product parameters will explain how much power (W) of the submersible pump is suitable for how much L H.

What is the formula for calculating the water pressure of a fish tank? How is it calculated.

The pressure of the water is based on the pressure formula. p=pgh shows that it is only related to the density of the water and the depth of the water. You give the tank a size, but the water is not necessarily full, so you have to measure the depth of the water and substitute it into the formula.

The density of water is 1000 thousand Li Dan Kepei cubic meters, g takes 10 n kg

Let's be honest about how to calculate it.

You don't understand this.

The size is long. High meters, high meters, calculate, water pressure, water pressure meters water column, about one atmosphere.
