How many cubic meters of gas is 5 cubic meters of gas at 1MPa pressure in a storage tank

The volume of gas contained in a 5 cubic meter tank at a pressure of 1 MPa can be calculated from the ideal gas equation of state. The ideal gas equation of state is a fundamental equation that describes the state of a gas, and it can be used to calculate the relationship between the pressure, volume, and temperature of a gas. The formula for the equation of state of an ideal gas is:

pv = nrt

where p is the pressure of the gas, v is the volume of the gas, n is the number of moles of the gas, r is the gas constant, and t is the temperature of the gas.

In this problem, we know that the volume of the tank is 5 cubic meters and the pressure is 1 MPa, and we need to find out the volume of the gas it contains. Since the number of moles and temperature of the gas are unknown, we need to deform the equation of state of the ideal gas to obtain a formula that contains only pressure and volume:

v = nrt/p

Since we only need to ask for the volume of the gas, we can consider the number of moles and temperature as constants, the gas constant r as known values, and the pressure and volume into the equation for calculation. Assuming that the mole number is n, the temperature is t, and the gas constant is r, substituting it into the formula yields:

v = nrt/p = nr(273+25)/(1*10^6) =

Thus, the volume of gas contained in the tank at a pressure of 1 MPa is cubic meters. It should be noted that this result is obtained under the assumption that the gas is ideal, and the state of the gas in the actual situation may be affected by a variety of factors, so the calculation results are for reference only.

1 liter = cubic, i.e. 1000 liters = 1 cubic. The gas tank 1000L is 1 cubic meter. Liters and cubic meters are volume units, in addition to liters and cubic meters, common volume units are milliliters, cubic decimeters, cubic centimeters, cubic millimeters, etc.

Among them, the capacity of 1 cubic decimeter is equivalent to the volume of a cube whose length, width and height are equal to 1 decimeter, which is the same as the volume of 1 liter, milliliters, cubic decimeters, cubic centimeters, cubic millimeters The conversion between cubic decimeters is: 1 cubic decimeter (dm 3) 1000 cubic centimeters (cm 3), 1 cubic decimeter (dm 3) 1000 milliliters (ml), 1 cubic decimeter (dm 3) 100000 cubic millimeters, etc.

National filing standards for gas storage containers.

The gas storage tank above 1m3 belongs to the special equipment gas storage tank, and the use needs to be reported to the local supervision and inspection department before it can be used, and the gas storage tank with a pressure of 10 kg below 1 cubic meter belongs to a simple pressure vessel, which is a product exempted from national inspection and does not need to be inspected.

1. If the gas storage tank does not meet the conditions of the pressure vessel, the tank is not a pressure vessel, so it can not be used as special equipment. If the gas contained in the gas tank is compressed air, the pressure is less than and the volume is less than 30L, it is not a pressure vessel and can not be managed as special equipment.

2. If the gas storage tank meets the conditions of the pressure vessel and belongs to the pressure vessel, the gas storage tank is a special equipment. If the gas in the gas tank is compressed air, the pressure is 1MPa, and the volume is 2000L, it belongs to the pressure vessel and should be managed according to special equipment.

1MPa = 1 10 6Pa, 1 standard atmosphere = , Pa (Pa) and MPa (megapascal) are all SI units of air pressure. The units of air pressure commonly used are Pa (Pa), millimeter mercury column height (mm·hg), and millibar (MB). The conversion relationship between them is:

100 Pa = 1 mbar 3 4 mm mercury column height. The instruments commonly used to measure air pressure in meteorological observation include mercury barometer, empty box barometer, and barometer.

Ask! How many cubic meters of air does it take for a cubic air storage tank to be pressurized to 8 kilograms.

Dear, hello, I am glad to answer for you: please! A cubic gas tank with a key to pressure stupid to 8 kilograms of air how many cubic meters of air.

Answer: Pro: One cubic gas storage tank is pressurized to 8 kilograms of air pressure, and the gas that can be stored is about one cubic atmosphere pressure. A rise or destruction with a cube exponent of 3 is the product of three identical numbers.

Mathematical Definition 1, the cube is also called the cubic power. Multiply three identical numbers, called the cube of this number, thank you for your patience. If you are satisfied with my service, please give a thumbs up, and once again wish you all the best!

Peace and joy!

Ask! How many cubic meters of air does it take for a cubic air storage tank to be pressurized to 8 kilograms.

Ask! How many cubic meters of air does it take for a cubic air storage tank to be pressurized to 8 kilograms. Hello, the pressure of the air compressor and the gas tank is the same.

8 kg air compressor with 8 kg air tank. Generally, the volume of the air storage tank is between 1 5 and 1 3 of the exhaust volume of the air compressor. 1 kilogram of compressed air is equal to about one cubic meter.

Oxygen and nitrogen are commonly used today at about 150 atmospheres. Other gases, such as liquid chlorine, liquid ammonia, and liquefied petroleum gas, will have a lower pressure than oxygen.

It should be emphasized that the gas cylinder only contains one type of gas and cannot be mixed.

The air pressure of a gas tank of 5 cubic decimeters is an air pressure. A grandson is equal to one cubic meter, and one cubic meter is equal to 100dm! Water is 1 cubic meter, which is 1 ton = 1000 liters of cubic meter and the cubic decimeter difference of 10 to the third power, which is 1000 times.

1 cubic decimeter of water = 1 kg = 1 liter = 1 kg of water, 5 cubic decimeters = 5 kg. 5 kg is about equal to 5 pressures!1 kg is equal to so 5 kg pressure is equal to!

One kilogram is one atmosphere, because one atmosphere is equal to 10 kilograms, then one kilogram is equal to one atmosphere. So a friend is a pressure. Five kilograms is a pressure.

The air pressure of a gas tank of 5 cubic decimeters is an air pressure. 1 kg pressure = 1 atmosphere = 1 * 10 5pa = so 100 kg pressure is 10 megapascals. "Kilogram pressure" is a commonly used unit of pressure in daily life, and "megapascal" is commonly used in academics.

This problem requires knowing the gas equation of state pv=nrt, where p is the pressure of the gas, v is the volume of the gas, n is the mass of the gas, r is the gas constant, and t is the temperature of the gas.

Assuming that the gas in this tank is an ideal gas, its equation of state can be reduced to pv=nkt, where n is the number of molecules of the gas and k is the Boltzmann constant.

The pressure p = 1 megapascal = 10 6 pa, the volume v = 3 cubic meters, and the temperature t = room temperature (about 300 k) are substituted into the upper ruler formula, and the number of molecules of the gas is solved

n = pv kt = 10 6 3) 300) Peixiang.

Because the number of molecules of the gas does not change, the volume of the gas can be calculated using the equation of state pv=nkt when the pressure becomes 1 megapascal

v'=nkt p = 300) 10 6 cubic meters.

Thus, when a 3 cubic tank is pressurized to 1 megapascal, the volume of gas in it becomes about a cubic meter.

According to the equation of state of an ideal gas, pv=nrt, where do hu p denote the pressure of the gas, v denotes the volume of the gas, n denotes the number of moles of the gas, r is the gas constant, and t denotes the absolute temperature of the gas. When the pressure of the gas increases from 0 (the standard condition, i.e. 1 atmosphere) to 1 megalosson, the volume of the gas becomes p1v1 p2 = 1 atm x 3 cubic meters) 1 megapascal x 100,000 pascal) cubic meters, which is about liters. So, a 3 cubic tank at a pressure of 1 megapascal has a gas volume of about liters.

A 3 cubic tank pressurized to 1 megapascal has 3 cubic gases. Because the hospital uses hidden wheel oxygen has two bad letters, one is the use of the ward, the pressure does not exceed, and the other is the use of hyperbaric oxygen chambers.

1 It is not possible to determine the difference.

2 Since it is not possible to determine the size of the tank and the amount of gas in place, it is not possible to determine the amount of gas after pressurization to 1 megapascal, nor the amount of gas remaining in the tank.

3 If the size of the tank and the amount of gas in place are known, the amount of gas pressurized to 1 megapascal can be calculated by the equation pv=nrt in the ideal gas state.

where p is the pressure, v is the volume of the skin, n is the number of moles of the substance, r is the gas constant, and t is the absolute temperature of the gas.
