Hi all, Many thanks for all the info. I have managed to get the problem simulated by a mate of mine and I think I'm going to go with an orifice plate to restrict my flow. Many thanks again.

Hi BigInch, Many thanks for your prompt response. I'm trying to calculate the area of the hole in the pipe and therefore have two unknowns (velocity and C.S.A.). I get the equation you have said but can't seem to get another so I can solve for the 2 unknowns.....

Hi all, I am designing a water circuit where water will be pumped around a cold water circuit. In order to protect the pumps a recirculation line will be installed where a % of the flow will be diverted in case there are any blockages downstream of the pumps. Flowrate down the 2" main line...

Hi all, I am trying to calculate the temperature I need to raise methane so that it doesn't begin to freeze once its pressure has been droped through a regulator via the Joule Thompson affect. I know the following conditions - upstream pressure, downstream pressure, downstream temperature to...

Hi all, Sorry for the delay in replying but just wanted to say many thanks for the tips. Think I will get the text book, will be worth the investment! Thanks again.

My understanding is that the compressibility factor Z is a function of both pressure and temperature which is what prompted my initial question. speco many thanks for suggesting the GPSA databook, this is exactly the sort of thing I was looking for. I'm always a bit hesitant on doing it online...

Hi pmover, Many thanks for your reply however I was hoping for an equation as I would rather calculate it by hand if I can rather than relying on the internet all the time. Keeps the brain working! I would assume I would use Pv = ZnRT but there are three variables so have been scratching the...

Hi all, Was wondering if someone could help me, I'm trying to calculate the actual density of natural gas under a certain pressure and temperature. I know the actual pressure and the actual temperature however I don't know the actual compressibility factor. Feedback would be much...

Hi Desertfox, Many thanks for the info. Not having ASME B16.5 to hand the webpage you directed me to clears up my initial assumption. Thanks again.

Hi all, I was wondering if you could clear up a point with all the various flange classes i.e. class 150, class 300 etc. Would you be able to explain the difference between the classes and when to use which?? I assume it's to do with pressures and temperatures.... Many thanks
