Pressurization time

[tdkoch]

Is it possible to calculate the time required to pressurize a container with air, given its volume and the inlet diameter and flow rate?

 

[jonralph]

Yes, it's possible. In the simplest terms One vessel volume will raise the pressure by one Barg (14.7 psig) so if you know the volume and the inlet flow it's a simple calc. There are other factors just depends how accurate you want to be.

 

[kmuhsen]

from ideal gase equation ( if applicable depending on the pressure) P-final x v-final = m RT

v : specific volume could be calculated.

by calculating the vessel size you can get the total mass ( M) of air charged into the vessel.

Assuming steady flow conditions Time = M / ( rate of flow)
