Hi,

Consider the link above to support your work .

You will need an orifice or a control valve to manage the flow . 

Note : what is the quantity accumulated in the head space to be  released ?

Good luck

Breizh

To you and others ,

In addition to my previous answer consider this paper prepared by a Forum member Mike Beychock who passed away a few years ago.

Good luck
