Problem with outlet pressure
 

I have problem with outlet pressure in my ansys fluent simulation. My simulation is gas leaking from pipe. The outlet pressure is not 1 bar, like it have to be. You can see that on pic that I posted. So does someone have some opinion about my plot, is it good or not and do you have any suggestions how can I fix problem with outlet pressure?
