actual gas的意思|示意

Actual gas is a term used to describe the physical gas contained in a gas stream. It is the actual volume of gas, not the theoretical ideal volume. This volume is determined by measuring the pressure and temperature of the gas.

The actual volume of gas is not the same as the standard volume of gas, which is typically measured at a temperature of 0°C (32°F) and pressure of 101.325 kPa (14.7 psia). The actual volume of gas will change depending on the temperature and pressure it is measured at.

In order to accurately measure the mass of a gas, the actual volume needs to be known. This is useful for activities such as determining the volumetric flow rate of a gas or measuring the mass flow rate of a gas. Knowing the actual volume of a gas stream can also be used in engineering calculations for pipelines or storage tanks.

There are several methods for determining the actual volume of a gas. One common technique is to use a device known as a rotameter. This device measures the pressure, temperature and volumetric flow rate of the gas stream. This information can then be used to calculate the actual volume of the gas.

In conclusion, the term “actual gas” is used to refer to the physical volume of a gas stream. This volume is determined by measuring the pressure and temperature of the gas. Knowing the actual volume of a gas stream is important when measuring the mass of a gas, measuring volumetric flow rate, and in engineering calculations.
