Yeah wasn't to bad to drive and it got a fair bit of looks. I liked the colour the windows could of been a little darker but I was about 23-24 when I got it.

Ok geniuses, or geni, never had to pluralise genius before because I thought I was the only one.

Anyway, who can tell me, or give me the formula to calculate pressure drop in a compressed cylinder?

I need to make a cylinder with 4" outlet, need to half fill it with water. Then pressurise it to 6 bar. Then crack the 4" valve and work out diameter/length of cylinder to ensure it doesnt run out of bar before it runs out of water.

Your question has been forwarded onto the appropriate department..

Couple questions though:

What is the gas that is being pressurised?

Can you sketch the layout of the cylinder? ie: If your valve is on the base it will guarantee the water flows out before the gas..

What is the size of the relief valve? You said you'd crack the 4" valve.. But a cracked 4" valve is gonna flow a helluva lot different to a fully opened one..

The 4" butterfly valve will be fully opened.

I think if got it now though.
