The pressure of the 5000 m3 LNG storage tank is reduced from 20 Kpa to 16 Kpa; the temperature of the tank is -162°C. What is the volume of gas released? What calculation formula should be used?
OP, you can use the gas equation for a preliminary calculation: PV=nRT
It is also necessary to know the tank liquid level; by using the ideal gas law to calculate the change in n, it is possible to estimate the amount of vented fluid
445 cubic units. Don’t ask me how I figured that out; I determined it through 100 attempts of emptying the container. The machine is stopped, with no liquid being added nor any loading taking place
Can you derive a formula based on the equation and the known data? I calculated it and it’s only half of yours; I’m a bit confused.

Calculations show that the ideal gas law is suitable for classroom exercises; it cannot be applied in practice in such a rigid manner
