Thanks for all the input and comments. bimr - not quite sure how I've not fully thought the scenario out. I am describing something that exists in reality and not a hypothetical design. As LittleInch says, the how/why is immaterial, hence my omitting the detail from the OP. Pumping would not...

Hopefully the attached sketch clarifies matters. http://files.engineering.com/getfile.aspx?folder=6b6ff819-b84c-4e19-87ea-ec53edb79572&file=diagram.png

Thanks for the reply BigInch. Why not Bernoulli though? The valve is of the gate type so the passage through which equalization flow takes place is essentially constant bore diameter. There isn't a published Cv value for this passage. I could attempt to calculate/estimate one though.

Greetings all, I wanted to carry out an analysis of the following scenario. A tall cylindrical container is located at depth subsea. This container is filled with water but these contents are maintained at a lesser pressure than the surrounding seawater. The interior of this container has an...

Looking into it in more detail, you can account for entrained air so perhaps this is what MikeHalloran means by "an air bubble".

I think I may be answering my own question now so it's more a case of getting some corroboration that I am not barking up the wrong tree! Looking at it with a fresh (ish!) pair of eyes, I used the definition of bulk modulus for K. Re-arranging to give me dP = -V (K/dV) where dP is delta P...

Some answers for you dberman. 2) A "no-go" is a restriction in the completion bore which will be a integral feature of one of its component parts eg top sub in the completion packer. The no-go is intended to be used to to determine position within the completion. 3) Bridge plug - basically a...

Greetings, This seems on the face of it a simple problem but for the life of me I can't seem to get a grip on it. I want to determine the pressure in a system after the system's volume has increased. Basically, a predefined volume has it's pressure increased to a certain pressure when this...

I’m looking at stress distribution in a cylinder which has several significant slots running along part of it’s length. I’d like to perform some illustrative calcs on it to establish some “independent” ratings to compare with those that I’ve obtained from several FEA analyses. One figure in...
