Is there any method for calculating the amount of gas required for container pressure testing?
Thread Content
For example, I have a tank that needs to be pressure-tested, and I want to calculate how much gas is required. Is there any way to do that?
The ideal gas law PV=NRT.. for reference..........
For example, for a 1000 m3 spherical tank with a design pressure of 1.6 MPa, which is equivalent to 16 kilograms of pressure; if 1000 m3 of gas is introduced into the tank, that corresponds to 1 kilogram of pressure. Therefore, 16 kilograms of pressure equals 16*1000 = 16000 m3.

The value obtained in this way represents the volume at normal pressure; generally, when the pressure of the compressed gas is higher, it can be calculated again to get the corresponding value. Of course, it can also be expressed in terms of moles or mass for convenience; at standard atmospheric pressure, a mole of gas occupies 22.4 liters. If I remember correctly
