Why is it necessary to know the compressibility factor of a gas when calculating throttling devices?
There are varying degrees of deviation between the gas density and the actual density at different pressures and temperatures, and the gas compressibility coefficient is the measure of this deviation. When calculating throttling devices, it is necessary to know the density of the fluid being measured, while the gas compressibility factor is an essential parameter for calculating the density of high-pressure gases.
It can be seen from the calculation formula for the throttling device that the density of the fluid being measured is a parameter required; moreover, the gas compressibility coefficient is a parameter used to calculate the density of gases, so it is necessary to know this compressibility coefficient.
